FITS Interferometry Data Interchange (FITS-IDI) Convention
The FITS Interferometry Data Interchange Convention is a set of conventions
layered upon the standard FITS format to assist in the interchange of data
recorded by interferometric telescopes, particularly at radio frequencies and
very long baselines. This convention is intended to separate a standard set
of conventions from those used within particular software packages such as
May 2009 by Eric Greisen (NRAO)
Date and Place of First Usage:
1997, by the VLBA (Very Long Baseline Array) system of radio telescope antennas
Extent of Usage:
This convention is in use for the VLBA telescope for data from the current
hardware correlator and the future software correlator and has also been used
with other correlators such as the Joint Institute for VLBI in Europe (JIVE)
correlator for the European VLBI Network.
Comments and/or critiques:
Sample FITS File:
The original FITS-IDI file was very large (112 MB) and contained 96843 samples with 4 Stokes, 4 IFs and 8 Spectral
channels per sample. The current file available here has been reduced in size by only preserving the
first 1000 rows in the TAPE_STATISTICS and UV_DATA binary table extensions.
Sample Header Listing:
