GBT Software Project Note 4.2
The common FITS format structure is presented for all GBT and related
data files. The device FITS files for the GBT are permanently
archived after each observation, and will usually be input to the
AIPS++ filler, which has the task of combining all scan data FITS
files into an AIPS++ Measurement Set. This data may then either be
processed further in AIPS++, or written out in an AIPS++ supported
FITS format (one of which is single dish FITS).
This document describes a set of keywords, a primary HDU, and three
binary tables (STATE, PORT, and DATA) which are common among
GBT FITS files.
A strategy for achieving this standard is proposed. Finally,
a list of GBT FITS files is given with short descriptions and
references as to their construction.
- 8th November 2001
- Penultimate definition of FITSVER 1.1; released
for general comment (Richard Prestage).
- 16th November 2001
- Final version agreed for implementation of
FITSVER 1.1. Cosmetic changes only c.f. 8th November 2001
version. Subsequent changes to the content of this document should
increment the document version number (Richard Prestage).
- 27th November 2001
- Added the BCPM to the list of devices that
produce FITS files in ``Description of GBT FITS Files'' (Amy Shelton).
- 2nd December 2004
- Changed the format of the value for keyword
DATEBLD to be FITS compliant for dates (Mark Clark).
