Photometric catalogs of 20 nearby galaxies covered by SPIRITS

<p>3.6, 4.5, 5.8 and 8.0 micron point-spread function photometric catalogs for the following 20 galaxies covered by SPIRITS (Spitzer InfraRed Intensive Transients Survey) -</p> <p>Fornax, Leo I, NGC6822, NGC185, NGC147, M32, IC1613, M110, WLM, IC342, M81, M83, NGC6946, M101, M106, M51, NGC6744, M63, NGC2903, M104</p> <p>For each galaxy, we performed psf photometry on&nbsp; archival Spitzer/IRAC 3.6 (ch1), 4.5 (ch2), 5.8 (ch3) and 8.0 (ch4) micron images (available at the <a href="https://sha.ipac.caltech.edu">Spitzer Heritage Archive</a>). Each datafile presented here is a catalog containing the coordinates, magnitudes and uncertainties in magnitudes of all sources detected in the 20 galaxies for a particular IRAC filter.</p> <p>Descriptions of columns in each datafile:</p> <p>Column 1 : Right Ascension of the source (degrees)</p> <p>Column 2 : Declination of the source (degrees)</p> <p>Column 3 : PSF magnitude of the source for the IRAC filter corresponding to the datafile. (mags)</p> <p>Column 4 : Uncertainty in PSF magnitude of the source (mags)</p> <p>Column 5 : x coordinate of the source in the image (pixels)</p> <p>Column 6 : y coordinate of the source in the image (pixels)</p> <p>Column 7 : PGC Name of the host galaxy of the source</p>
