FIGURE CAPTIONS

Figure 1. Schematic overview of Ginga database pipeline processing.

Fig1 description above



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 channels.

Fig2 description above



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.

Fig3a description above

Fig3b description above



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.

Fig4 description above



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.

Fig5 description above



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.

Fig6 description above



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 (line).
