How do you tell APP to apply bias correction to your flats and/or flat darks only?
Wayne
Hi Wayne @whixson,
APP will apply bias and/or dark flat Masters to your flats if they are available. If they are not, APP will give you a warning that you will not be able to get good flat-field correction without bias and/or dark flats available.
So APP will automatically do this correctly, you will only need to supply the bias and/or dark flats and they will be used 😉
Kind regards,
Mabula
Thanks Mabula, what if I don’t want to apply bias to the lights but only the flats?
Hi @whixson, then you will first need to create the masterflat with the bias loaded.
Then remove the bias and masterbias and load the lights...
But... why would you want to do this ? The light need to be calibrated with either bias or darks.... otherwise flat-field calibration will not work.
What would be an argument to not use bias for lights?
