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.
