Scientific paper
The authors describe the two-dimensional photometry reduction program DoPHOT which is designed to reduce images automatically. They describe how the program iteratively finds and classifies objects, updates the PSF, and fits the current best-estimate of the PSF to all stellar images. The shortcomings and advantages of the approach used by DoPHOT are discussed in some detail. The flexibility of the code is demonstrated by the wide variety of scientific problems that are being successfully addressed with the help of DoPHOT. Finally, the authors present future plans for changes and improvements of the code.
