Photometric Color Calibration
« on: 2018 January 27 23:16:07 »
Hi,

I am busy reprocessing some images with PCC and notice the following error in the Process Console.  The process completes successfully, so maybe it is just a cosmetic thing.

Catalog stars: 1941

485 star(s)
256 PSF fittings
Found 5 stars with invalid position

Any ideas or thoughts.

Hi all,

I'm having the same issue and searching for an answer ended up here (there isn't anything else online on the subject). Has anyone else encountered the problem? What does it mean? Has it been solved?

Thanks.

I can not reproduce this problem and analyzing the code I can't find a case where this fails. I would need a image where this is happening and the parameters used in PCC.

Hi,

The error/issue seems to have disappeared.  The only change I have done in PCC was to enable "Force plate solving" and "Ignore existing metadata"
