Next: Combine Example Up: Preparing Your Calibration Previous: Combining Flat Fields . The procedure is similar to the flat field combining procedure, except that you may want to scale the sky level using the mean, median or the mode of the intensity distribution or taking into accoun the exposure time. Hence, in the combining, like in the case of combining flat fields, correct weighting of the frame is important. ... Table: Keywords for combining sky calibration frames . ...
