ImageIntegration, ImageCalibration etc.
« on: 2014 March 24 01:13:29 »
Hello,

I am doing my first image calibration, integration etc. in PixInsight. Following the advise on the website (https://pixinsight.com/tutorials/master-frames/index.html) I have collected a large number of bias, dark and flat frames (about 100 each) and about 10 hours of H-alpha data for the rosette nebula. When I integrated the bias frames following the steps given on the link given above, I find three files being generated and they are: Integration, rejection_low and rejection_high. Since the rejection_high is the last file generated, I presume that, that is the master bias file. But presumptions are not always correct. Can someone tell me if I am right? If not, which one is the master bias file?

Thanks in advance,

Regards,

Shekhar

Hi Shekhar,

as the name implies, in the rejection-files there is the rejected data which is not used in the integrated picture. There is all data of the single images which is different from the rest. You can say, it is the rubbish.
In your case the Integration-file is the masterbias.

Greetings
Tobias

Thanks, Tobias! That certainly sounds more logical than my logic. Thanks a lot for the quick response.
