GINGALAC ivo://nasa.heasarc/gingalac NASA/GSFC HEASARC LEDAS 2026-10-02 NASA/GSFC HEASARC help desk heasarc-vo at athena.gsfc.nasa.gov Observation The GINGALAC database table contains a summary of the contents of the Ginga pointed observations. 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 GINGA LAC 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 in 1999 as part of an archive exchange between the data centers. The original version was updated in October 2008, when the positions (which had been created assuming the wrong equinox) were corrected; in addition, the values of the nh parameter were corrected. This is a service provided by NASA HEASARC . https://heasarc.gsfc.nasa.gov/W3Browse/all/gingalac.html Archive Research served-by HEASARC TAP
