The Leicester Ginga Archive: Raw Data Archive

The original Ginga First Reduction Files (FRFs) are available through the LEDAS database table GINGAFRF. This database, made using the ``kiroku'' (or log sheets), is the best route for accessing the raw data. You can select data according to pointing direction, bit rate, operating mode, observation date etc. to locate all FRFs belonging to one observation. The GINGAFRF database table contains one entry per slot start or end time (i.e. a new entry occurs every time there is an Earth occultation, ground station pass, electron belt passage etc.). The FRFs containing all the selected slots may be extracted using the xp command from within BROWSE or by clicking on the FRF names in ARNIE. A full description of the database table is available from both BROWSE and ARNIE.

The default sample of the GINGAFRF database table contains only the pointed data. If you are interested in slewing or scanning data then you need to select the total sample with the BROWSE command csam total; this sample is not accessible with ARNIE.

Once you have obtained your raw data, you will need a copy of the Leicester Ginga Data Analysis Software to produce spectra and light curves of the source.
