psf: Analytic function solution failed to converge

ping zhao wrote on Aug 12, 2011

Hello,
I am running task
psf under daophot

For most of the images is runs fine. But for a couple of images, it took unusually long time and at the end it failed, with a message:
"Analytic function solution failed to converge"

What does it mean? How do I fix this?

Thanks,

Ping
