GBT data begins life as a series of raw FITS files written by each device manager into the project directory of the observer.

A typical data set is organized as follows:

/home/gbtdata/projectname

The project name is a directory tree containing the following directories, each with FITS files from that device:

• Antenna
• GO
• IF
• LO1A
• LO1B
• Rcvr2_3 (or other receiver-specific directories)
• backends - can be any combination of:
  • DCR
  • Spectrometer
  • SpectralProcessor
  • Holography * ScanLog.fits - this is a file containing references to all of the files generated by the devices for each scan.
