Photometric Color Calibration Failed
« on: 2018 May 20 17:40:48 »
Hi,
This is the first time PCC fails for me.
*** Error: Insufficient photometric data: Got 0 sample(s); at least 5 are required.
Plate solve works fine. The detected stars images show a lot of stars. I went from -3 to 0 for sensitivity with no difference. I use auto for magnitude
The log shows everything is fine until getting to extracting the color data
*******************************
Photometry process finished:
3 of 3 images processed successfully.
0 images with errors.

*** Error: Insufficient photometric data: Got 0 sample(s); at least 5 are required.
Reading swap files...
1719.806 MiB/s
<* failed *>

I have no idea what I am doing wrong and need some guidance
The link below is to the xisf color image (M101_RGB.xisf)

Thanks in advance

The error is that the color calibration section(Photometry) does not enough usable samples in the simplest term. Here is your initial error(far left) and then I change from 'Automatic limit magnitude' to setting the limit higher, in this case I just started at 17. The image is then processed without error.
