RA/DEC Disappears from file after undo

Software Siril
1

I had previously posted a topic in which I said that the RA/DEC disappears upon conversion to 32b, but I was unable to reproduce the problem. I have finally reproduced it and it doesn’t have anything to do with conversion, but rather the “undo” button. I have tried this with several files and gotten the same result. When I open the fits file, the RA/DEC is in the header, and if I go to photometric CC, it finds the coordinates. If I then do an image processing function such as “remove green noise” and then undo it, the photometric CC no longer finds the RA/DEC. If I display the fits header it appears to still be there but if I now save the file, the new file does not have RA/DEC in the header.

Here is an example of a file where this happens (the “before” file):
r_pp_Sunflower Galaxy_stacked.fits (66.9 MB)

Here is the “after” (remove green noise, then undo):
r_pp_Sunflower Galaxy_stacked after.fits (66.9 MB)

I’m not sure if anyone has looked at this. It is an easily reproducible problem. I am using the latest Siril version and running under Windows 11. Here is the log when I start with the “before” file above, run “remove green noise”, then “undo”, then attempt photometric color calibration. When the color calibration panel comes up it’s clear there is no RA/DEC metadata even though it is in the original file FITS header. I clicked on “OK” anyway just to get the final line in the log.

Hi,

the forum has been down for a few days so it may well be we have missed your post :slight_smile:
Thanks for your report. This issue was known and has been fixed for next release.

Cheers,

Cecile
