Chandra XRay Observatory CXC 1 Comparison of RGS

Chandra X-Ray Observatory CXC 1. Comparison of RGS Model for 1 E 0102. 2 -7219 to the HETG data 2. BI CCD CTI Correction for ACIS Paul Plucinsky, Dan Dewey, & Joseph De. Pasquale Paul Plucinsky 1 EPIC Cal October 2006

Chandra X-Ray Observatory CXC Gratuitous Pretty Pictures of E 0102 S 3 Summed Data ~100 ks RGS Spectrum (Pollock 2006) Objective: develop a spectral model which can be used by RGS, HETG, EPIC & ACIS, etc. Paul Plucinsky 2 EPIC Cal October 2006

Chandra X-Ray Observatory CXC What’s New Since the Iceland 2006 Meeting? • Pollock’s model based on the RGS data has been used by Dan Dewy of the HETG team to compare to the HETG data • Dan adopted the RGS spectral model, including the normalizations • Dan developed a spatial model for the structure of the remnant • He created simulated datasets to compare the against the MEG and HEG data from the Chandra HETG The overall agreement is encouraging !!! • Good agreement on the bright lines, some disagreement on the weaker lines All of the following work has been done by Dan, many thanks !!!

Chandra X-Ray Observatory CXC Where Do We Go From Here ? • Dewey analysis needs to be updated with latest response files for HRMA/ACIS/HETG • Line-based analysis needs to be updated with the latest response files for HRMA/HETG/ACIS • RGS data need to be re-analyzed with new background model for RGS • RGS and HETG teams agree on a model well before the IACHEC meeting in California • ACIS, MOS, and pn use the new model to fit the CCD spectra Paul Plucinsky 9 EPIC Cal October 2006

Chandra X-Ray Observatory CXC 2. CTI Correction in CIAO for S 3 and S 1 • Penn State CTI corrector available since 2001 • CXC response products for S 1 and S 3 used a position-dependent gain correction which recovers the true values of the PHs but does not improve the spectral resolution • S 3 and S 1 data will now be CTI-corrected in the events files provided to GOs • All TEN CCDs will be CTI-corrected as of CIAO and CALDB release in December 2006 • small, but significant improvement in spectral resolution and QE uniformity Paul Plucinsky 10 EPIC Cal October 2006
