Well, the master bdark was 32 bit and the original 16 bit, what should they be?
Edit: saving the master dark in 16 bit fixed it, but in ccdstack there are several 16 bit options, should it be saved as 32 bit anyway?
Edit again: I saved the master in ccdstack as 16 bit signed and it looked too black in ccdsoft. As 16 bit unsigned in ccdstack and it looked as it should in terms of contrast in ccdsoft. As 32 bit float and it displayed as all white, and lastly as 32 bit integer in ccdstack and it was the same as 16 bit unsigned in ccdsoft. Which one is best? I also better start reading the ccdstack manual
.
I will also read
this thread.
thanks
