NUMBER: 422 MODULE: daophot.psf SYSTEM: V2.11 DATE: Mon Apr 19 10:49:29 MST 1999 FROM: davis BUG: In rare circumstances the psf task can crash with a floating point error when computing the analytic portion of the psf. So far this has only been observed on Linux systems but it could potentially be a problem for other machines as well. STATUS: The problem is caused by division by a very small number in the weight computation and happens when the point being added to the fit is very close to fitrad pixels from the center of the analytic function. There is no true workaround but changing the value of fitfit slightly or choosing another analytic function may avoid the problem.
