-This is demonstrated here. The above shows the difference in PSF magnitude as a function of x position on the stack for two reductions of the same stack (30204). One is the provided cmf file, the other is our own run of psphot (code from SVN as of Nov 25th 2009) on 30204. Note the shift in difference with x.
+One potential problem is demonstrated here. The above shows the difference in PSF magnitude as a function of x position on the stack for two reductions of the same stack (30204). One is the provided cmf file, the other is our own run of psphot (code from SVN as of Nov 25th 2009) on 30204. Note the shift in difference with x. It must be said that there is no such shift between 29871 and 30204.
