Good morning,
I'm using APP 1.075 beta4 to calibrate and integrate images taken on a Canon 5D MkIV DSLR and see this message during integration.
09:54:18 - 6) INTEGRATE: integrate light frames: wrote frame: 8 to file mapper

09:54:22 - 2) CALIBRATE: Adaptive Data Pedestal: enabled
09:54:22 - 2) CALIBRATE: Adaptive Data Pedestal set at: 9.761E-03
09:54:22 - 2) CALIBRATE: WARNING !!! we have detected a possible sensor offset issue between the MasterBias and the Masterdark !
09:54:22 - 2) CALIBRATE: WARNING !!! the MasterBias has a median value of: 3.125E-02 for channel 1
09:54:22 - 2) CALIBRATE: WARNING !!! the MasterDark has a median value of: 3.112E-02 for channel 1
09:54:22 - 2) CALIBRATE: WARNING !!! normally, the median value of the MasterDark should be the same or larger than the median value of the MasterBias
09:54:22 - 2) CALIBRATE: WARNING !!! because a dark should always contain the entire bias signal plus the dark current and possible amp glow signals
09:54:22 - 2) CALIBRATE: WARNING !!! some CMOS sensors however exhibit this behaviour due to CMOS technology.
Details of the DSLR raw files are:
40 x 240 second Lights, 20 x Flats, 20 x Darks, 50 x Bias. Everything was shot at iso800 and same sensor temperature
Anything I should be doing different during the calibration or is this message fairly typical?
best regards
Kev
Hello.
I have the same console message.
MBP, OS Mojave
APP 1.075 beta4
Canon 60d, ISO 800
Lights 17x 360s
Darks 26x 360s
Bias 40x 1/125s
Flats 40x 1/13s
DarkFlats 40x 1/13s
What is wrong?
Best regards
Mariusz
Nothing, it is a warning, however the values are the same or very close to being the same. It shouldn't impact the result.

Thank you Vincent. I'll continue to ignore it 🙂
