"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.

Here the sol 89 results, based on the two-color pyrometer algorithm described above, and the Sol 89 REMS RDR data, without correction of systematic errors, no bugs assumed:
The green curve in the top diagram describes the inferred absolute Kelvin temperature by record (not by time), averaged (all weights set to 1) over 40 samples. Absolute temperature was restricted to a range between 100 and 400K before averaging. The bottom diagram describes the inferred emissivities, also averaged over 40 samples. Emissivities were restricted to a range between 1e-20 and 100 before averaging. The algorithm leaves one degree of freedom, e.g. the emissivity quotient. It is set to 1 in this run, meaning grey body assumed. The absolute emissivity values look rather confusing to me, because I expected them to be between 0.9 and 1.0, and constant over time. On the other hand, absolute temperature values look rather reasonable for less noisy regions (sufficiently high brightness temperatures). Any of my attempts to get more reasonable-looking emissivities by adjusting emissivity quotients, absolute value of one of the emissivities, or wavelengths failed, because other values became less reasonable. Some calibration of the absolute temperature is possible by adjusting the difference of the wavelengths. |
