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.
