07 Nov 2006 CALDB version 3.2.4 has been released. This release contains ACIS time-dependent gain calibration files only. See the How CALDB 3.2.4 Affects Your Analysis section of the CIAO release notes and the CALDB release notes for details. 31 Jul 2006 New webpage: Effective Area Cross-calibration Results Involving the Chandra X-ray Observatory This webpage provides a discussion of cross-calibration work relating the Chandra X-ray Observatory to other X-ray missions, particularly XMM-Newton. Much of this webpage was developed in cooperation with the XMM-Newton calibration team. |
Timing AnalysisIn order to perform absolute timing analysis on a dataset, a barycenter correction must first be applied to the data. One may then create lightcurves and phase-binned spectra to look for variability in the source. These threads also provide information on working with data taken in the ACIS continuous clocking (CC) mode.
