DPhot
Purpose: DPhot finds and measures point sources and extended sources for IRAC and MIPS. A linear leastsquares fit to the flux values in the BCD frames yields the bestfitting set of flux densities and shapes of the observed objects.

DPhot finds and measures point sources and extended sources for IRAC and MIPS. The program places a closelyspaced grid (small fraction of FWHM) over the area of interest and writes a matrix in which each coefficient is the flux value at a BCD data pixel due to a PRF at a grid point. A linear leastsquares fit to the flux values in the BCD frames yields the bestfitting set of flux densities and shapes of the observed objects. DPhot uses no prior positions or templates and uses the BCD flux values without a mosaic.
