      Bias and Dark Current

      Dark subtraction (covered here) and flat fielding (covered in another lecture) are the primary calibration steps for removing instrumental defects from your science images. This lecture discusses the reason for bias and dark current in your sensor, shows some of the typical defects in these images, and gives guidelines as to how many calibration images to take and how to create master frames.
