"February 27, 2013. MSL Release 1, part 1, Sols 0-89.
The first release of MSL data takes place in two parts. Part 1, February 27, 2013, includes raw data products (EDRs) acquired on Sols 0 through 89, August 6 through November 5, 2012, for these instruments: APXS, ChemCam, DAN, Hazcam, Navcam, and REMS, along with SPICE data. Part 2, March 20, 2013, will include the derived data products (RDRs) for Sols 0 though 89 for the APXS, ChemCam, DAN, Hazcam, Navcam, and REMS instruments, along with both the EDRs and RDRs for the CheMin and RAD instruments, and the RDRs for the SAM instrument. Release 1 does not include data from the MAHLI, MARDI, or Mastcam instruments. These instrument teams have not yet delivered data products to PDS. Some documents in the MSL archives are awaiting clearance by JPL Document Review and/or the JPL Import/Export Control Office. They will be posted online as soon as clearance has been received, and announced on this web site." Phil -------------------- ... because the Solar System ain't gonna map itself.

I'll answer the easy questions first:
Most of the noise can be averaged away by appropriate low-pass filters, if it is purely statistical, because temperature changes are slow; the simplest way to do it, is just averaging over a few dozens of samples; a more advanced way is using appropriate regression curves. Example for simple averaging over 40 samples: Again based on this Sol 89 REMS RDR file. About warm-up I know just that little info from the FMT-file; it referes to pressure data: QUOTE OBJECT = COLUMN COLUMN_NUMBER = 63 NAME = "PS_CONFIDENCE_LEVEL" DESCRIPTION = "String representing the confidence level for the pressure sensor; 0 = bad; 1 = good; - Byte 0: Warm up effect (only for barocap 1) 0 = warm up effect; 1 = no warm up effect; - Byte 1: Shadow effect; 0 = shadow effect; 1 = no shadow effect;" DATA_TYPE = CHARACTER START_BYTE = 568 BYTES = 8 END_OBJECT = COLUMN Warm-up seems to take 180 seconds at the beginning of each series of measurements, at least on sol 89. |
