I suspect this question reflects a lack of understanding about bpm's! I have no problem with the processes of creating a bpm, creating master files or a fully integrated stack of data. When I create a bpm am just loading flats without any bias frame calibration and darks of course - is that right?
Pam
Hi Pam,
So you load in your flats, darks and bias for the bpm creation. For the darks it's best to take your longest exposures.
Ok - got it.
Thanks for such a speedy response Vincent!
Pam
You're welcome. I am going abroad again though so this might be my last week of speedy responses. Hope I'm online asap after that though.
No worries Vincent. However! I remain confused about some aspects of creating a bpm. Sarah Wager, in her tutorial simply loads flats and darks using hot pixel kappa of 2 and cold pixels 50% albeit in an older version of APP than I am using. When I do the same I get a calibration warning that 'to be able to perform accurate flat field calibration the provided flats need to be calibrated by (in my case) a masterbias of the same ISO/gain value as the flat frame.' If I create a master bias and load that together with flats and darks I don't get that message - is that right?
I notice that Sara Wager when looking at the details of her bpm suggests that the bad pixel percentage and hot pixel percentage should be around 3% whereas mine is 2.483% - is that ok or is something amiss?
Pam
Hi Pam,
Yes that's fine, I'm note sure but it might be that Sara already calibrated her flats... or it's a change from past versions. Anyway I include them and the masters are created including the BPM. Those percentages are fine, you can try to use the BPM instead of a masterdark in previous data to see if it's effective.
Thanks again Vincent - I will check out by using a bpm instead of a masterdark on earlier data.
