Comments and errata: 1. A revised spectral calibration model has been applied to data starting in the Release 3 bundle. A known discontinuity exists in the wavelength calibration between the Raman and fluorescence regions (at SCCD pixel 500). ------------------------------------------------------------ Release Number: 2 Release Date: 2021-11-22 Data Coverage: 2021-05-21 through 2021-08-21 (Sol 90-179) New products have been added to these collections: urn:nasa:pds:mars2020_sherloc:data_aci urn:nasa:pds:mars2020_sherloc:data_raw urn:nasa:pds:mars2020_sherloc:data_intermediate urn:nasa:pds:mars2020_sherloc:data_processed urn:nasa:pds:mars2020_sherloc:data_watson Products have been revised in these collections: None. Comments and errata: 1. Labels for raw data may include Source_Product_Internal references to themselves. These label errors will be corrected in a later release. 2. Where Source_Product_Internal appears in intermediate and processed labels, the LIDVID 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. 3. In labels for raw, intermediate, and processed non-imaging data, the product 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 version_id is different. This label error will be corrected in a later release. ------------------------------------------------------------ Release Number: 1 Release Date: 2021-08-20 Data Coverage: 2021-02-18 through 2021-05-20 (Sol 0-89) New products have been added to these collections: urn:nasa:pds:mars2020_sherloc:data_aci urn:nasa:pds:mars2020_sherloc:data_raw urn:nasa:pds:mars2020_sherloc:data_intermediate urn:nasa:pds:mars2020_sherloc:data_processed urn:nasa:pds:mars2020_sherloc:data_watson urn:nasa:pds:mars2020_sherloc:document Products have been revised in these collections: None. Comments and Errata: 1. There are several description fields with TBD in data product labels. The labels will be updated in a future release. 2. In labels for raw, intermediate, and processed non-imaging data, the product 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 version_id is different. This label error will be corrected in a later release. 3. Labels for raw data include the class Source_Product_Internal, which is inappropriate for EDR data. Where Source_Product_Internal appears in intermediate and processed labels, the LIDVID 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. 4. In the labels for raw, intermediate, and processed products containing spectral data, the spectral channels are described as separate fields. In a later release labels will be revised to describe the spectral channels as a group of related fields, for greater usability. ******** SECTION B ******** This section is for general notes and errata. 1. SHERLOC measurements on Sols 4 and 11 were commanded using the cruise flight software, which restricted the size of some SHERLOC measurements. Downstream processing resulted in 40 EDR products (ERA, ERB, EPA, ESP), all associated with a 1000 pulse measurement. 2. Internal AlGaN measurements are typically associated with the ECA/ECB/RCS product IDs, however, due to command restrictions, EDRs and RDRs associated with sequence ID SRLC16000 that use the ERA/ERB/RRS product IDs are also internal AlGaN measurements.
