Background

All GBT scan data FITS files should conform to the standards specified in the GBT Software Project Note 4.0, ``Device and Log FITS Files for the GBT.''

The holography backend will be used for engineering observations related to the performance of the antenna, by recording the phase difference between the main and reference beam. GBT memo 101 describes the holography backend hardware.

The details of the holography backend FITS files are described in the following sections.
