SUMMARY OF SEQUENCE NUMBER 290027
Title: GRATINGS CALIBRATION OBSERVATION OF AN EMISSION LINE SOURCE: CAPELLA
Observer: CALIBRATION
Subject Category: Normal Stars and WD
Seq: 290027 ObsId: 00058
Long-term Plan bin: 8-Mar-2000
ABSTRACT
The RS CVn star Capella is the brightest coronal emission line source in the sky. The X-ray spectrum of Capella exhibits strong emission lines over most of the LETG and HETG energy bands. These observations will be used to determine the LSF for the HRC-I/LETG and ACIS-S/HETG at many energies and orders. These observations will be conducted simultaneously with EUVE observations which can observe Capella anytime between 9/14 and 3/7. The integration times reflect an additional 100 ksec required for the emission-line project.
