Chandra ACIS / XMM-Newton EPIC cross calibration using HIFLUGCS sample
Gerrit Schellenberger is leading a project whereby the HIFLUGCS cluster sample (Reiprich & Böhringer, 2002, ApJ, 567, 716) is used to examine the effective area cross-calibration uncertainties between Chandra/ACIS and XMM-Newton/EPIC instruments.
