SUMMARY OF SEQUENCE NUMBER 790022
Title: IN FLIGHT CALIBRATION OF THE HETGS EFFECTIVE AREA AND CROSS DISPERSION PROFILE
Observer: Marshall
Subject Category: Active Galaxies and Quasars
Seq: 790022 ObsId: 00461
Long-term Plan bin: 20-Jan-2000
ABSTRACT
The targets 3C 273 and Cyg X-2 are well-studied continuum sources that we propose to observe as calibration targets. The QSR 3C 273 has been observed for calibration purposes by XTE, SAX and ASCA simultaneously, so a cross-calibration with these missions would be possible if any of them can be available when AXAF observes 3C 273. In the case of Cyg X-2, its spectrum is relatively well known and it is known to be point-like, so that cross dispersion profiles can be measured.
