"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.

Have you tried this on the time series yet? In one of the press conferences they had a chart of ground temperature vs. time that could be used as a rough check. Another issue would be how best to deal with the noisy raw data.
On the "warm up" effect--what does that refer to exactly? Like when the readings are taken after an idle time of an hour or so? Looks like they normally take readings every second for a few minutes every hour, with occasional longer stretches. -------------------- |

Have you tried this on the time series yet? In one of the press conferences they had a chart of ground temperature vs. time that could be used as a rough check. The simplified answer is: No, not yet, but a good idea for a better calibration. A little more detailed: I also looked at the UV data. They are less noisy. I tried to get a 5-point absorption spectrum of atmospheric trace gases, that form or degrade after sunrise. For this I had to do a very detailed analysis. Doing this, I also found a jiggering caused by truncation of numeric values, and indications for superposed sinus oscillations with a period of about 300 to 350 seconds of unknown origin, might be due to my way of data analysis, may be due to data analysis done by the REMS team, or due to technical properties of the sensors, like a combination of inductivity and capacity. Similar systematic errors may also occur for brightness temperature data. Accurate results for absoute temperatures can only be obtained, after those systematic effects are annihilated. Therefore I was focussed on that. The only thing I had been doing, was dividing the Sol 80 EDR raw thermopile A/B data to see, whether they can be used as two-band pyrometer data, and it looked good, but calibration wasn't available to me. It will take me a while to elaborate things in more detail. |
