Figure 1. Schematic overview of Ginga database
Figure 2. The pulse height spectra from 20 to 35 keV for
the top- and mid-layers of detectors 1 and 2. The collimator silver
line is visible from channel 35 to channel 37. The increase in count
rate beyond channel 32 is due to the re-binning of spectral
Figure 3. The (a) SUD rate versus PI_MONI rate and (b)
SUD rate versus LAC top-layer count rate in the energy range 2-10 keV
for a source and background observation respectively. These plots were
produced after data rejection so that the linear relationships between
the parameters are seen.
Figure 4. The attitude corrected LAC top-layer count rate
in the energy range 2-10 keV, SUD and SOL2 rates, DELTXZ offset and
the collimator transmission versus time for a source observation.
Figure 5. The result of fitting the background subtracted
and attitude corrected source data to a simple absorbed power-law
model. Both the LAC top- and mid-layer spectra are shown.
Figure 6. The light curves in the energy band 2-6 keV for
both the top- and mid-layers. The time axis is in hours starting from
the beginning of the observation.
Figure 7. The reconstructed photon spectrum for a source
observation of unusable quality. The top- (crosses) and mid-layer
(dots) are shown together with the best-fit power-law spectrum
