16 November 1982Drift Scan Observations With A Charge-Coupled Device (CCD)
A new procedure has been developed of using a Charge-Coupled Device (CCD) that entirely eliminates the need for flat field calibration exposures and therefore avoids the limitations inherent in conventional flat fielding methods. This paper describes the procedure, its advantages and disadvantages and the data processing steps that are needed. Examples of images at various stages are given as are the first results of background galaxy counts to an equivalent J magnitude of about 25m6.
