During the course of the MSL mission the MAHLI science team may update previously released data products or documentation; for example, updates may occur due to changes in calibration data or procedures. Updates will be reported in this file. Older versions of data and documentation will not be retained in the archive. Section A of this file contains an entry for each MSL release with general information about the contents of the release. Updates to previously released files are reported in these entries, along with any known errata.

The following products were created with incorrect PICNOs for the following reason: sequence:mhli00468, sol:895 Assigned PICNO range Expected PICNO range -------------------------- -------------------------- 0895MH0000000000302751I01- 0895MH0046800000302751I01- 0895MH0000000000302770I01 0895MH0046800900302770I01 0895MH0000000000302752C00 0895MH0046800100302752C00 0895MH0000000000302762C00 0895MH0046800100302762C00 sequence:mhli00469, sol:895 Assigned PICNO range Expected PICNO range -------------------------- -------------------------- 0895MH0000000000302771I01- 0895MH0046900000302771I01- 0895MH0000000000302780I01 0895MH0046900900302780I01 0895MH0000000000302772C00 0895MH0046900100302772C00 Reason: The sequences, mhli00468 and mhli00469, were mistakenly commanded with tracking ID 0. The result is that neither the sequence ID nor the sequence line (command counter) were included in the PICNO, which is why the PICNO is populated with zeros. 2. Unintentional dark images due to unreasonable exposure parameters chosen for nighttime imaging sequence:mhli00444, sol:808 PICNO CDPID --------------------------------- ----- 0808MH0004440000300750I01 750 0808MH0004440010300751{C,I}0{0,1} 751 0808MH0004440020300752I01 752 0808MH0004440030300753{C,I}0{0,1} 753 Reason: These images are completely dark due to incorrectly commanded exposure settings that did not allow the exposure to go long enough for the scene required. 3. Out of focus images likely due to camera movement during acquisition sequence:mhli00408 & mhli00409, sol:883 PICNO range CDPID range -------------------------- ----------- 0883MH0004080000302619{C,I}0{0,1} 2619 0883MH0004080030302622{C,I}0{0,1} 2622 0883MH0004090000302627{C,I}0{0,1}- 2627-2630 0883MH0004090030302630{C,I}0{0,1} sequence:mhli00473, sol:910 PICNO range CDPID range -------------------------- ----------- 0910MH0004730000303033{C,I}0{0,1}- 3033-3036 0910MH0004730030303036{C,I}0{0,1} Reason: These images are out of focus as a result of camera movement (e.g., wind) that occurred when the images were acquired rather than a commanding error or the camera failing to find focus. **************************************************************** **************************************************************** ******** SECTION B ******** This section is provided for general notes concerning the archive as a whole. 1. When acquiring video products, the product for the first frame captures values for the current state of the rover. However, all subsequent frames within that video retain the rover state values from the first frame. As a result, some values are not accurate after the first frame. The following values within the xml and INDEX files for video products will be set to nil: xml --------------------------------- Under the attribute: Product_Observational:Observation_Area: Discipline_Area:Imaging:Instrument_State: Device_Temperatures:Device_Temperature: device_name for DEA HEAD_FPA ELECTRONICS ELECTRONICS_A ELECTRONICS_B the keywords: temperature_value temperature_status Under the attribute: Product_Observational:Observation_Area: Discipline_Area:geom Geometry: geom Geometry_Lander: geom Derived_Geometry the keywords: geom solar_azimuth geom solar_elevation INDEX ----------------------------- Under the attribute: Product_Observational:Observation_Area: File_Area_Observational:Table_Delimited: Record_Delimited:Field_Delimited:name INSTRUMENT_TEMPERATURE:FPA INSTRUMENT_TEMPERATURE:OPTICS SOLAR_AZIMUTH SOLAR_ELEVATION 2. Clarification of the "sequence_id" in the data product .xml file versus the "Sequence ID" in the Product Identifier described in the MMM PDS Data Product Software Interface Specification (SIS) As stated in the File Naming Convention section of the SIS, the first six digits of the product identifier (Sequence ID) are reflected in the sequence_id keyword value in the data product label file (.xml). This is the case when the Mastcam data are downlinked via the original sequence that acquired the data as recorded in the product identifier. Occasionally, the data are requested to be downlinked differently than acquired (e.g., a different compression); this is done by sending a new sequence, which is recorded in the sequence_id. In this case, the FSW inserts the new sequence information into the sequence_id keyword value. As a result, the first six digits of the product identifier (as originally acquired) and the sequence_id keyword value (as downlinked) are not the same. 3. In Releases 0001-0011, the version ID in the PICNO (see section 3.4.1 of MSL_MMM_EDR_RDR_DPSIS.PDF) does not necessarily match the daily, operational version of the same product. Due to the fact that there can be multiple versions of a product (e.g., partials) received during operations, this value is incremented for each version of a product received. However, for PDS archiving, when applicable, only the full and complete version of a product is archived which will receive the lowest version ID possible for that type of product. In most cases, this is a value of 1. As a result, the PDS products archived in Releases 0001-0011 do not necessarily reflect the same version ID seen in the corresponding final, complete version of a daily, operations-received product. To account for this, lookup tables which correlate the operational PICNO to the PDS PICNO for Releases 0001-0011 have been provided in the miscellaneous_MSLMHL directory. There is one table for EDR and one table for RDR products. Starting with Release 0012, all full versions of every operationally- produced product will be available in the MAHLI PDS volume, and partial products will be taken into consideration when assigning the PICNO version number. This will ensure that all PICNOs in the PDS volume match with the corresponding daily, operational version of the same product. 4. For each frame of a GOP, various keywords within the INDEX and xml files are only partially accurate due to the way the camera hardware operates. The camera only returns the coarse SCLK and not the fine SCLK, and as a result, the fine SCLKs need to be estimated with software. This estimate will not necessarily reflect the actual time in which the frames were acquired.
