ACTPol Point Source Catalog
The file ACTPol-D56_sources.fits is a FITS table that contains the catalog of sources detected in the ACTPol map of the region which we call Deep56 (D56) observed during the second season (2014) of ACTPol observations. This region covers 680 square degrees of the sky between Declination -8.8 and 5.2 degrees and RA greater than 352 degrees and less than 40.6 degrees. The 2014 (S14) D56 catalog includes 581 sources above a 148 GHz flux density limit of 10 mJy (before deboosting) that were detected at a significance larger than 4.5-sigma in total intensity. The completeness and purity of this catalog are both greater than 97% above 10 mJy. Measurements of the Stokes Q and U amplitudes are reported for 169 sources that are brighter than 30 mJy in total intensity. Measurements of fractional polarization are reported for 65 sources, 25 of which were detected at a significance larger than 3-sigma in polarized intensity. Polarization angle measurements are also reported for these 25 sources following the IAU standard for polarization angle. The FITS table includes the information from Table A4 in the paper titled Two-season ACTPol Extragalactic Point Sources and their Polarization Properties (2018), arXiv, MNRAS. It can be read into Python using the astropy.table module.
The files ACTPol-D5_sources.fits and ACTPol-D6_sources.fits are FITS tables that contain the catalog of sources detected in the ACTPol maps of the regions which we call Deep5 (D5) and Deep6 (D6) observed during the first season (2013) of ACTPol observations. The D5 region covers 181 square degrees of the sky between Declination -3.8 and 4.8 degrees and RA greater than 350 degrees and less than 4.6 degrees. The D6 region covers 160 square degrees of the sky between Declination -8.4 and 0 degrees and RA between 26 and 42 degrees. The 2013 (S13) D5 and D6 catalogs include 132 and 235 sources above a 148 GHz flux density limit of 7 mJy and 5 mJy, respectively, that were detected at a significance larger than 4.5-sigma in total intensity. The completeness and purity of these catalogs are greater than 90% and 98%, respectively. Note that the D5 and D6 catalog tables do not include all columns from the list above.
