This table has been produced from the raw Ginga LAC First Reduction Files (FRFs), and contains information of the individual pointings in addition to FITS spectra and light curves, HDS and FITS data cubes and the plots produced during the pipeline processing. These products can be used with either the Ginga data analysis software or the <a href="/docs/xanadu/xanadu.html">XANADU software suite</a>. This archive (database and all the associated products) is a copy of the GINGABGD data products held at the Leicester Data Archive Service (<a href="http://ledas-www.star.le.ac.uk/">http://ledas-www.star.le.ac.uk/</a>). It was delivered to the HEASARC as part of archive exchange between data centers to facilitate the data transfer across the Atlantic.
