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: CHEMIN EDR PRODUCT TYPES UPDATED FOR THIS ARCHIVE: CHEMIN EDR This release includes new products from Sols 90 through 179, and revised products from Sols 0 through 89. All CHEMIN 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. 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: 2013-02-27 DATA COVERAGE: 2012-08-06 to 2012-11-05 (Sols 0-89) PRODUCT TYPES RELEASED FOR THIS ARCHIVE: CHEMIN 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. CMIN_EDR_SIS.* - The MSL CheMin EDR Software Interface Specification ******** SECTION B ******** This section is provided for general notes concerning the archive as a whole. When validating with PDS VTool, some data products produce the validation error, "'FILM_TABLE' does not contain required object 'COLUMN'". This is a false error due to a bug in VTool. 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. The archive contains a few empty (zero-byte) data files, which represent observations that were planned but for which no data were collected. These empty files have associated PDS labels. The CheMin team chooses to leave them in the archive as a record that the observations were planned.
