SUMMARY OF SEQUENCE NUMBER 590037
Title: CALIBRATION OF HETGS USING THE CRAB PULSAR AND NEBULA
Observer: Marshall
Subject Category: SN, SNR, and isolated NS
Seq: 590037 ObsId: 00169
Long-term Plan bin: no LTS bin
ABSTRACT
The spectrum of the Crab nebula and pulsar have been studied by virtually every X-ray astronomy mission in the last 20 years. The spectrum is stable and is relatively well known, so we propose to use it to calibrate the HETGS system, looking primarily for an overall agreement with other X-ray telescopes. The ACIS continuous clocking mode will be used so that the pulsar can be time resolved.
