Sub-Frame Selector Script for calibration frames?

[Jfakatselis]

Attended Vicent Peris' workshop this past weekend in Cambridge, MA. It was terrific! Thank you so much Vicent and don't forget our host Joe DePasquale  at the Harvard Smithsonian Center for Astrophysics.

One of the group suggestions was perhaps the addition of a script like the sub frame selector but that would examine flats, bias, and darks for consistency before they are just blindly used in calibrating lights.

The present script works to review noise, median, etc but goes through the unnecessary steps to look for stars in the image. Naturally these cal frames would not contain stars and this step would not be needed.

So, the suggestion is would it make sense to have a sub-frame selector type script for cal frames rather than only lights. What does the larger user group think?

Hi Jim, thanks.

I put here three graphs from the script after analysis of 25 dark frames. Some of them were shoot after flat frames, so there is some RBI in them. This signal is clearly seen in the graphs, and in one of the frames is very severe, so adding this functionality would be really nice.

I'm sorry but at the workshop I forgot that there was a region of interest option. Anyway, as Alejandro says, it would be good to have a "from preview" option.


Best regards,
Vicent.
