CCD Detectors

 

The description of CCD reductions is divided into four parts. Section gif describes the ideas behind the relative calibration of 2--dimensional photometric CCD--images.

Section gif gives a description of the steps required to perform a relative calibration of the CCD and discusses the various MIDAS commands that are available to perform the required operations. Section gif provides some examples of typical reduction scenarios. Section gif is a summary of the relevant commands.

The procedures described in the manual will yield CCD--frames whose pixel values represent relative flux from one to the other. In order to proceed to calibrate the images in terms of magnitudes requires further steps not detailed here.
