It is updated with each release of HELICAM data. Section A of this document contains an entry for each release with general information about the contents of the release, in order from newest to oldest. Updates to previously released files are reported in these entries, along with any known errata. Section B of this file contains general notes, if any, concerning the archive as a whole. ******** SECTION A ******** Release Number: 9 Release Date: 2024-03-29 Data Coverage: 2023-08-31 to 2024-01-01 (Sols 900-1019) New products have been added to these collections: urn:nasa:pds:mars2020_helicam:data urn:nasa:pds:mars2020_helicam:browse 1. Heli filenames are incorrectly populated with a ROVER_MOTION_COUNTER POS value of 1. The correct ROVER_MOTION_COUNTER POS value can be found in the Sequence ID field of the filename or the ROVER_MOTION_COUNTER Keyword in the label. 2. The INSTRUMENT_SERIAL_NUMBER in Heli labels are incorrect. The INSTRUMENT_SERIAL_NUMBER should be 6001 for Heli Nav and 6002 for Heli RTE. 3. Many of the vertical-projection mosaics of the landing sequence made from helicopter navigation camera images are misnamed. They incorrectly say 003 after the product type. This field is Site number for rover mosaics but is supposed to be Flight number for helicopter mosaics. The correct flight number is in the free-form field of the filename. For example in V_MMMM_0533_RAS_0030000_VRT_S_F30LS01J01.IMG the free-form field is F30LS01 which means Flight 30 Landing Sequence image 01. The flight number can also be inferred from the input or source product IDs. All landing projection mosaics earlier than flight 34 have this problem; all of those after flight 60 are correct. In between, some are correct and some are not. ------------------------------------------------------------ Release Number: 8 Release Date: 2023-11-27 Data Coverage: 2023-04-30 to 2023-08-31 (Sols 780-899) New products have been added to these collections: urn:nasa:pds:mars2020_helicam:data urn:nasa:pds:mars2020_helicam:browse 1.

The INSTRUMENT_SERIAL_NUMBER in Heli labels are incorrect. The INSTRUMENT_SERIAL_NUMBER should be 6001 for Heli Nav and 6002 for Heli RTE. 3. Some of the Helicopter Navcam vertical projection frames, made of the landing sequence, have incorrect filenames, identifying it in the RMC field as flight 3 rather than the correct flight number. The comment field of the filename correctly identifies the flight number. This should be fixed on flights 34 and later but will not be corrected in earlier flights. ------------------------------------------------------------ Release Number: 6 Release Date: 2023-03-24 Data Coverage: 2022-8-27 to 2022-12-28 (Sols 540-659) New products have been added to these collections: urn:nasa:pds:mars2020_helicam:data urn:nasa:pds:mars2020_helicam:browse 1. We are now delivering late arriving data products, which were received outside the sol range in previous releases. 2.
