Redelivered xml labels for CP2, CA2, and RMI to correct offsets. Delivering data_calibrated_audio not previously delivered for Sols 72, 79, 81, 96, 349, 384, and 537. Release Number: 6 Release Date: 2023-03-24 Data Coverage: 2022-08-27 to 2022-12-28 (Sols 540-659) New products have been added to these collections: urn:nasa:pds:mars2020_supercam:data_calibrated_audio urn:nasa:pds:mars2020_supercam:data_calibrated_spectra urn:nasa:pds:mars2020_supercam:data_observation_log urn:nasa:pds:mars2020_supercam:data_radcal_rmi urn:nasa:pds:mars2020_supercam:data_raw_audio urn:nasa:pds:mars2020_supercam:data_raw_rmi urn:nasa:pds:mars2020_supercam:data_raw_spectra urn:nasa:pds:mars2020_supercam:data_special_rmi Products have been revised in these collections: urn:nasa:pds:mars2020_supercam:calibration_supercam urn:nasa:pds:mars2020_supercam:data_derived_spectra urn:nasa:pds:mars2020_supercam:data_observation_log urn:nasa:pds:mars2020_supercam:data_special_rmi urn:nasa:pds:mars2020_supercam:document Updated some files in calibration_supercam collection that had incorrect target name, and redelivered rmi mosaics that were missing point annotation. While validating Release 6 data_calibrated_audio, data_raw_audio, data_radcal_rmi and data_calibrated_spectra collections, we notice that all the ca2 and cp2 files as well as all the rmi cdrs previously delivered had incorrectly calculated offsets so some of the HDU headers and tables. The data in this release (sol 540-659) have been corrected. The data for previous releases will be corrected in release 7. In the data_raw_audio collection for sols 0-539, EA0 product labels do not match the specified table definition. The labels incorrectly order LASERDATA HEADER and LASERDATA TABLE after SOUND HEADER and SOUND TABLE. The labels will be corrected in release 7. Release Number: 5 Release Date: 2022-11-21 Data Coverage: 2022-04-26 to 2022-08-26 (Sols 420-539) New products have been added to these collections: urn:nasa:pds:mars2020_supercam:calibration_supercam urn:nasa:pds:mars2020_supercam:data_calibrated_audio urn:nasa:pds:mars2020_supercam:data_calibrated_spectra urn:nasa:pds:mars2020_supercam:data_derived_spectra urn:nasa:pds:mars2020_supercam:data_observation_log urn:nasa:pds:mars2020_supercam:data_radcal_rmi urn:nasa:pds:mars2020_supercam:data_raw_audio urn:nasa:pds:mars2020_supercam:data_raw_rmi urn:nasa:pds:mars2020_supercam:data_raw_spectra urn:nasa:pds:mars2020_supercam:data_special_rmi Products have been revised in these collections: urn:nasa:pds:mars2020_supercam:calibration_supercam urn:nasa:pds:mars2020_supercam:data_calibrated_audio urn:nasa:pds:mars2020_supercam:document urn:nasa:pds:mars2020_supercam:data_calibrated_spectra urn:nasa:pds:mars2020_supercam:data_derived_spectra urn:nasa:pds:mars2020_supercam:data_observation_log RAMAN calibrated spectra (CDRs) from sol 0-419 have been reprocessed using an algorithm developed by the SCAM team to automatically remove spikes present on the data. The SuperCam_PDS_Userguide has been updated to document the changes to the RAMAN processing. The labels for data in the calibration_supercam collection have been updated to replace the TBDs with additional information about the samples. We have also added some additional data to the calibration_supercam collection. The labels for the wave files sol 180-418 in the data_calibrated_audio collection have been updated in response to the incorrect Observation_information identified in Release 4. The description of several of the MU SOH values in most of the SuperCam CDRs were incorrectly set to 0. This has been fixed for future releases. Also, the degree notation for the MU SOH values was incorrectly noted as -51¡C, and should be -51°C. Release Number: 4 Release Date: 2022-07-22 Data Coverage: 2021-12-23 to 2022-04-25 (Sols 300-419) New products have been added to these collections: urn:nasa:pds:mars2020_supercam:data_calibrated_audio urn:nasa:pds:mars2020_supercam:data_calibrated_spectra urn:nasa:pds:mars2020_supercam:data_derived_spectra urn:nasa:pds:mars2020_supercam:data_observation_log urn:nasa:pds:mars2020_supercam:data_radcal_rmi urn:nasa:pds:mars2020_supercam:data_raw_audio urn:nasa:pds:mars2020_supercam:data_raw_rmi urn:nasa:pds:mars2020_supercam:data_raw_spectra urn:nasa:pds:mars2020_supercam:data_special_rmi Products have been revised in these collections: urn:nasa:pds:mars2020_supercam:document urn:nasa:pds:mars2020_supercam:data_calibrated_spectra urn:nasa:pds:mars2020_supercam:data_derived_spectra urn:nasa:pds:mars2020_supercam:data_observation_log The IRS (CP2) and VIS (CP3) derived data products have been revised for the entire collection (Sols 0-299). For the IRS spectra the changes included: (1) application of a thermal calibration, (2) addition of a standard deviation calculation to the Quality Flag HDU and (3) correction of the saturation flag. For the VIS Calibration Data products, relative reflectance was calculated using observations of the AluWhite98 calibration target from either Sol 20 or Sol 184, depending on the number of red rows used (keyword REDROWS in the CP3 files). The AluWhite98 reference spectrum included corrections for geometry in the same manner as that for the IRS, i.e., compensations for the distance from the sun and solar incidence angle. Relative reflectance was calculated for files where either averaged spectra (“statistics”) or all spectra were acquired. Two corresponding HDUs were added to the FITS CDR (HDU 10 and 11, labeled as SPECTRA_REFLECTANCE and STATISTICS_REFLECTANCE). While validating Release 4 data_calibrated_audio collection we notice that some of the wave files (.wav) have incorrect information in the mars2020:Observation_Information. This will be corrected in a future release. ------------------------------------------------------------ Release Number: 3 Release Date: 2022-03-22 Data Coverage: 2021-08-22 to 2021-12-22 (Sols 180-299) New products have been added to these collections: urn:nasa:pds:mars2020_supercam:data_calibrated_audio urn:nasa:pds:mars2020_supercam:data_calibrated_spectra urn:nasa:pds:mars2020_supercam:data_derived_spectra urn:nasa:pds:mars2020_supercam:data_observation_log urn:nasa:pds:mars2020_supercam:data_radcal_rmi urn:nasa:pds:mars2020_supercam:data_raw_audio urn:nasa:pds:mars2020_supercam:data_raw_rmi urn:nasa:pds:mars2020_supercam:data_raw_spectra urn:nasa:pds:mars2020_supercam:data_special_rmi Products have been revised in these collections: urn:nasa:pds:mars2020_supercam:document urn:nasa:pds:mars2020_supercam:data_calibrated_spectra urn:nasa:pds:mars2020_supercam:data_derived_spectra urn:nasa:pds:mars2020_supercam:data_observation_log urn:nasa:pds:mars2020_supercam:data_special_rmi The Raman derived data product, a table of features, has been added to the data_derived_spectra collection. The SuperCam EDR-RDR SIS document has been revised to include information about this product, but further revisions will be forthcoming. Several files that were previous delivered in the data_special_rmi collection have been removed (SCCT and sky observations) because the automated processing code is not yet optimised and the mosaics are not of sufficient quality. The directory structure of the calibration_supercam collection has been reorganized. Some top-level directories have been moved to subdirectories to conform to the description in the SuperCam Bundle SIS. ------------------------------------------------------------ Release Number: 2 Release Date: 2021-11-22 Data Coverage: 2021-05-21 to 2021-08-21 (Sols 90-179) New products have been added to these collections: urn:nasa:pds:mars2020_supercam:data_calibrated_audio urn:nasa:pds:mars2020_supercam:data_calibrated_spectra urn:nasa:pds:mars2020_supercam:data_derived_spectra urn:nasa:pds:mars2020_supercam:data_observation_log urn:nasa:pds:mars2020_supercam:data_radcal_rmi urn:nasa:pds:mars2020_supercam:data_raw_audio urn:nasa:pds:mars2020_supercam:data_raw_rmi urn:nasa:pds:mars2020_supercam:data_raw_spectra urn:nasa:pds:mars2020_supercam:data_special_rmi urn:nasa:pds:mars2020_supercam:calibration_supercam (new) urn:nasa:pds:mars2020_supercam:document Products have been revised in these collections: urn:nasa:pds:mars2020_supercam:data_calibrated_audio urn:nasa:pds:mars2020_supercam:data_calibrated_spectra urn:nasa:pds:mars2020_supercam:data_radcal_rmi urn:nasa:pds:mars2020_supercam:data_special_rmi urn:nasa:pds:mars2020_supercam:document Labels for all SuperCam Release 1 data in these collections have been modified to change Source_Product_Reference to Internal_Reference. IRspec data (CP2 products) from Release 1 have been removed from the archive and replaced with new CP2 products for Sols 0-89. The replacement products have been updated to include: - computing the solar reference spectrum F_sky for that particular observation (including correction for the solar incidence angle and solid angle) - computing I/F using F_sky above as a reference - correcting residual atmospheric absorption that were still left, especially in long distance observations, and early-morning observations. The replacement CP2 products include some that were not delivered in Release 1 because of glitches in the data. These are now delivered with flags in the Glitches table in the FITS data files. The SuperCam User Guide and SuperCam Bundle SIS in the document collection have been updated. Errata: - In collections data_calibrated_audio, data_calibrated_spectra, data_radcal_rmi, and data_special_rmi, product labels include an Internal_Reference tag to indicate the source product from which the given product was derived. The LID given for the source product is incomplete. To locate the source product in PDS, use the given LID with ".fits" appended. - Collection data_radcal_rmi includes one product from sol 54, which was inadvertently omitted from Release 1. - Collection calibration_supercam is new in Release 2. Data product labels in this collection include "TBD" in a description field for the calibration target, which will be updated in a later release. ------------------------------------------------------------ Release Number: 1 Release Date: 2021-08-21 Data Coverage: 2021-02-18 to 2021-05-20 (Sols 0-89) New products have been added to these collections: urn:nasa:pds:mars2020_supercam:data_calibrated_audio urn:nasa:pds:mars2020_supercam:data_calibrated_spectra urn:nasa:pds:mars2020_supercam:data_derived_spectra urn:nasa:pds:mars2020_supercam:data_observation_log urn:nasa:pds:mars2020_supercam:data_radcal_rmi urn:nasa:pds:mars2020_supercam:data_raw_audio urn:nasa:pds:mars2020_supercam:data_raw_rmi urn:nasa:pds:mars2020_supercam:data_raw_spectra urn:nasa:pds:mars2020_supercam:data_special_rmi urn:nasa:pds:mars2020_supercam:document Products have been revised in these collections: None. Notes and Errata for Release 1 1. There are several description fields with TBD in the EDR labels. The labels will be updated in a future release. Appendix F in the SuperCam User Guide lists the descriptions. 2. The RAMAN, TRLS, VIS and IR derived products have not been peer reviewed so will be delivered to PDS in a future release. 3. The SuperCam_PDS_Userguide will be updated in future releases as needed. 4. SuperCam raw audio and raw spectra labels are missing the Observing_System_Component class that identifies the SuperCam instrument. The labels will be corrected in a future release. The missing class is as follows. Spectrometer and Micro-Imager Suite (SuperCam) Instrument urn:nasa:pds:context:instrument:mars2020.supercam is_instrument 5. In SuperCam raw audio and raw spectra labels, the byte offset to the first object in the data file, PRIMARY HEADER, is set to 1, but should be 0. The first byte in the file is Byte 0. All other byte offsets in the labels are correct. 6. In SuperCam raw audio and raw spectra labels, the product's version_id and the Modification_Detail version_id should be the same. In most cases the Modification_Detail version_id is 1.0 even if the product's version_id is different. This label error will be corrected in a later release. 7. SuperCam raw audio and raw spectra labels include the class Source_Product_Internal, which is inappropriate for raw data and may be ignored. Where Source_Product_Internal appears in labels for processed data, the LIDVID (logical identifier and version identifier) reference may have an incorrect version number, or may not include the complete logical identifier of the source product. These label errors will be corrected in a later release. ******** SECTION B ******** No general notes to report.
