Operation Requirements on Other Instruments

Aspect data from Tauvex will be critical to achieve the best performance of the SXRP. Observations of bright point sources made with the HEPC or FRD in the same SODART tube as the SXRP, i.e. while the SXRP is not operating, will be needed to correlate the Tauvex aspect solution with the true SODART aspect. During the performance verification phase the SXRP will be used with the HEPC in the other SODART tube to monitor the SRG/SODART aspect.

For scientific observations, SXRP will be most effective if used in conjunction with MART and with SIXA, to monitor the complex time-dependent spectral evolution exhibited by sources like Her X-1. If required by limitations in the SODART aspect control, the SXRP will be used with the HEPC in the other SODART tube to monitor the aspect.
