ACIS Science Instrument Team Report

The Science Instrument (SI) Calibration Report for the Chandra CCD Imaging Spectrometer (ACIS) is the very Basis of our ACIS calibration. It is prepared and updated by the ACIS teams at MIT and Pennsylvania State University, Co-Editors are Marshall W. Bautz (MIT), John A. Nousek (PSU), ACIS instrument PI is Gordon P. Garmire (PSU), see page to the right. The report is quite lengthy, therefore instead of pointing to the original Project Science Calibration page entry, the report was broken up into single sections containing each main topic in a separate page entry.
