to one of the CCDRED types given as an argument or queried:
object, zero, dark, flat, comp, illum, fringe, other
The following are CCDRED parameters which may be translated. You are
queried for the image keyword to use or it may be typed after the command.
An optional default value (returned if the image does not contain the
keyword) may be typed as the second argument of the command.
