Sanders Program Title: SCOSMOS Program IDs: 20070+30143 MIPS Bands: 24mic Release: -------- README (this file) scosmos_mips_24_GO3_200810.tbl photometry catalog mips_24_GO3_sci_10.fits 24mic image mips_24_GO3_unc_10.fits 24mic uncertainty map Images: The 24 microns images were produced by subtracting a constant background convolved with the residual pattern from the scan mirror from the BCDs, and taking the median at all sky positions. Given that data was obatined at three differents epochs, this ensures that the asteroids are filtered out. An average image was also computed at the time (not delivered), and its corresponding uncertainty is delivered as well, as an indication of the uncertainty at each position. Both images units are MJy/sr. The astrometric solution uses pixels of 1.2" that are aligned to within 0.1% with the pixels of the optical COSMOS datasets, with 1 MIPS 24 pixel corresponding to 6 optical grid pixels.
