Just a quick question. I processed some data recently and created 120 second dark frames and biases. When I ran calibration it seems to accept the biases but I get a warning message about no correlation between the dark frames and the lights and doesn't appear to use the darks. I am using a master dark and both the darks and lights are binned at 1, 2048 x 2048 pixels.
Can anyone please tell me why I am getting this error message?
Thanks
Albert
