Revisions were made to their labels to correct errors discovered in the keyword, STOP_TIME. STOP_TIME was being set by the EARTH_RECEIVED_TIME value which is incorrect. A code change was made, to use SCLK instead, which resolved this issue. RELEASE NUMBER: 2 RELEASE DATE: 2013-06-10 DATA COVERAGE: 2012-08-06 to 2013-02-03 (Sols 0-179) PRODUCT TYPES RELEASED FOR THIS ARCHIVE: APXS EDR PRODUCT TYPES UPDATED FOR THIS ARCHIVE: APXS EDR All APXS EDR products from Sols 0 through 89 have been revised and re-released. Revisions were made to their labels to correct errors discovered in the data processing. Revised products may be identified by the label keyword PRODUCT_VERSION_ID, which will have a value greater than 1.0, and by the keyword PRODUCT_CREATION_TIME, which will have a value later than the previous release date of February 6, 2013. Note: the APXS EDR data set is classified by PDS as "IN LIEN RESOLUTION" because there are still minor liens on this data set resulting from the peer review. The team is working to resolve the liens. OPGS Processing Issue Description: ---------------------------------- The millisecond value of the SCLK was incorrectly computed for all instrument EDRs since sol 0. Specifically, only 2 digits of the millisecond value were being extracted from the source telemetry data product (DP) for the following keywords: MSL:LOCAL_MEAN_SOLAR_TIME (all instruments) MSL:TELEMETRY_SOURCE_SCLK_START (all instruments) SPACECRAFT_CLOCK_START_COUNT (non-imaging instruments only) SPACECRAFT_CLOCK_STOP_COUNT (APXS, MAHLI and Mastcam ML0/MR0 images) For example, for the data product label, file NLA_412503611EDR_M0060000NCAM00533M1.LBL : Current values: MSL:LOCAL_MEAN_SOLAR_TIME = "Sol-00169M14:40:14.027" MSL:TELEMETRY_SOURCE_SCLK_START = "412503611.034" Correct values: MSL:LOCAL_MEAN_SOLAR_TIME = "Sol-00169M14:40:14.271" MSL:TELEMETRY_SOURCE_SCLK_START = "412503611.341" This 2-digit value was then incorrectly 0 padded with a zero right after the decimal place. Therefore, there is always a 0 value in the tenths position of the Fine portion of the SCLK. All data products affected have a 0 in the tenths digit for these keywords. To calculate the correct 3-digit milliseconds value, the following calculations can be performed. For MSL:LOCAL_MEAN_SOLAR_TIME the correct value is (idph.sclk_subseconds/ 2**16) then concatenated to 5 digits. For SPACECRAFT_CLOCK_START_COUNT(for imaging DPs) the correct value is (idph.sclk_subseconds/2**12) * 0.000954 then converted to integer(nothing after decimal point) and finally concatenated to 3 digits. This issue will be corrected for Release 3. RELEASE NUMBER: 1 RELEASE DATE: 2013-02-06 DATA COVERAGE: 2012-08-06 to 2012-11-05 (Sols 0-89) PRODUCT TYPES RELEASED FOR THIS ARCHIVE: APXS EDR PRODUCT TYPES UPDATED FOR THIS ARCHIVE: None The following documents in this archive are awaiting clearance by JPL Document Review and/or the JPL Import/Export Control Office and will be posted online as soon as clearance has been received. APXS_EDR_SIS.* - The MSL APXS EDR Software Interface Specification Calibration data will be available in the APXS RDR archive, to be released March 20, 2013. APXS EDR data files have a four-byte checksum field at the end of the file that is not described by the PDS label. This will be added to the labels for MSL Release 2, May 30, 2013. Labels for APXS EDR data products in this release erroneously list the value UNK (unknown) for these keywords: OBSERVATION_ID COORDINATE_SYSTEM_INDEX ORIGIN_OFFSET_VECTOR ORIGIN_ROTATION_QUATERNION REFERENCE_COORD_SYSTEM_INDEX ARTICULATION_DEVICE_ANGLE The labels will be revised to show the correct values for these keywords in Release 2. ******** SECTION B ******** This section is provided for general notes concerning the archive as a whole. 1. Some documents in this archive appear in Portable Document Format (PDF) files. PDF files can be read using free software available at www.adobe.com. PDS requires that a PDF document be accompanied by an ASCII text version; however, this has not been done for some PDF files in this archive because the documents contain figures, tables, equations, or other content that cannot be rendered as ASCII text. HTML is sometimes used as an alternative to plain ASCII, but in this case suitable HTML versions that captured all the content of the PDF could not be created. 2. The CONTACT_SENSOR_STATE keyword is hardcoded to "OPEN" for all product labels in the archive. Correct values for the contact sensors are incorporated in the binary data files and can be determined using the APXS_EDR_CWA_HEADER.FMT or APXS_EDR_SCI_HEADER.FMT files. 3. Release 11 redelivers all previous data from Releases 1-10. A correction was made to fix an issue in the PDS labels where the start time had a later value than the stop time.
