FITS Convention (Under Review)
FITS Interferometry Data Interchange (FITS-IDI) Convention
-
Description:
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
AIPS.

-
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.

This large (112 MB) sample FITS-IDI file contains 4 Stokes, 4 IFs and 8 Spectral
channels per sample and there are 96843 samples. Note: there are 4 extra 2880-byte
blocks of data at the end of this file that should be ignored.
