NAME

asnphot -- plot magnitude as function of subpixel position

USAGE

asnphot association

PARAMETERS

association
calnicb style association input file with list of images to be processed and co-added.
istar
star to be used for the photometry. This number corresponds to the stars marked with the asnalign task.
annulus, dannulus, apertures
parameters passed to qphot
datfile
optional ASCII output file which lists subpixel position and magnitude.

DESCRIPTION

Calls "qphot" to perform photometry on the same star in each image of an association. The results are plotted as a function of the sub-pixel position of the star center. The task requires that "alignasn" has been run on the association in order to define the stars to be used and in order to measure accurately the shifts between images.
