Next: Combining Flat Fields Up: Preparing Your Calibration Previous: Combining Bias Frames . Similarly to the bias combination one can obtain an average dark current frame. However, one should consider whether the dark correction should really be applied: one needs a reasonable number of dark frames in order not to degrade the S/N, and obviously this takes telescope time. ... In that case, provided a good linearity of the CCD, one could do with the subtraction of an average dark frame. ...
