Error in Demetra Preprocess

Post by Richard Brown »

Hi,
When doing data reduction with Demetra when I did the 'Preprocess' I ran the 'series' of 'object' and I got an error-"Error while computing preprocess image". The images looked OK and when I ran the data reduction of a previous star that evening there was no problem. What could the problem be?
Thanks
Dick

Hello Dick,

Can you post the process log message too ? maybe there will be more details ?

Hi Nicolas, Thanks for the reply. I found the problem-my dark frame exposure was not long enough and I corrected it.
Thanks
Dick
