H II phot : AUTOMATED PHOTOMETRY OF H II REGIONS APPLIED TO M 51

We have developed a robust, automated method, hereafter designated HIIphot, which enables accurate photometric characterization of H II regions while permitting genuine adaptivity to irregular source morphology. HIIphot utilizes object-recognition techniques to make a first guess at the shapes of all sources, then allows for departure from such idealized “seeds” through an iterative growing pro...
