SMOG Image Delivery - January 2016 - 1.2" pixel mosaics Background matching and gradient correction done l=100.9 deg through 110.2 deg, b=0.0 to 3.0 deg 3.1x3.7 deg & 3.1x3.8 deg images This SMOG mosaic data release is comprised of 1.2" pixel mosaics of the 12 second frametime IRAC BCD frames for l=100.9 through 110.2 deg. The angular size of the native resolution tiles are 3.1 deg x 3.7 deg and 3.1 deg x 3.8 deg. Data from SSC pipeline processing version S18.5 were used in making the images. Background matching and gradient correction were done on these images. The background matching and gradient correction improves offsets between AORs and removes many of the frame pull-ups near bright sources. This processing may be removing real sky variations so we provide these images *in addition* to the images that do not have the background matching. See the SMOG Data Description Document for more information about this processing. SMOG was a 4-visit cryogenic Spitzer survey. For a quick-look of the images, we provide 3-color jpeg files (IRAC bands 1 [3.6] blue, 2 [4.5] green and IRAC band 4 [8.0] red for each area covered by the FITS files. These are rebinned to much lower resolution to make the files small. Each mosaic fits file is about 411 MBytes. jpeg files are up to around 1 MBytes per file. Each mosaic fits file has an associated .hdr file which contains the fits header from the fits file and additional information about the individual frames included in the mosaic image. For example, the associated .hdr file for corr_SMOG_10800+0145_mosaic_I2.fits is corr_SMOG_10800+0145_mosaic_I2.hdr. ========================================================================================= SMOG areas (l=100.9 to 110.2 deg; b = 0 to 3 deg) 3.1x3.7 deg mosaics (ch 1,2,4) (deg) (deg) mosaic fits file associated jpg file longitudes covered latitudes covered ----------------------------------- -------------------------------- ------------------ ----------------- corr_SMOG_10200+0145_mosaic_I1.fits corr_SMOG_10200+0145_3.1x3.7.jpg 100.9 to 103.55 -0.40 to +3.30 corr_SMOG_10200+0145_mosaic_I2.fits corr_SMOG_10200+0145_mosaic_I3.fits corr_SMOG_10200+0145_mosaic_I4.fits corr_SMOG_10500+0145_mosaic_I1.fits corr_SMOG_10500+0145_3.1x3.7.jpg 103.45 to 106.55 -0.40 to +3.30 corr_SMOG_10500+0145_mosaic_I2.fits corr_SMOG_10500+0145_mosaic_I3.fits corr_SMOG_10500+0145_mosaic_I4.fits corr_SMOG_10800+0145_mosaic_I1.fits corr_SMOG_10800+0145_3.1x3.7.jpg 106.45 to 109.55 -0.40 to +3.30 corr_SMOG_10800+0145_mosaic_I2.fits corr_SMOG_10800+0145_mosaic_I3.fits corr_SMOG_10800+0145_mosaic_I4.fits 3.1x3.8 deg mosaics corr_SMOG_11100+0145_mosaic_I1.fits corr_SMOG_11100+0145_3.1x3.8.jpg 109.45 to 110.2 -0.45 to +3.35 corr_SMOG_11100+0145_mosaic_I2.fits corr_SMOG_11100+0145_mosaic_I3.fits corr_SMOG_11100+0145_mosaic_I4.fits
