Abstract

The grid PRF photometry method Dphot detects and measures point sources and extended sources using the Basic Calibrated Data images from the Spitzer Space Telescope without prior source position information. A mosaic is not used. Point sources with separations as small as 1.0 arcsec can be detected and measured. Examples of Dphot photometry are presented for 47 Tuc, the Galactic Center, Einstein Cross, and galaxies in GOODS North.
