 0.35-8.0 keV image from an 89 ks ACIS-S3 observation with the proposed extraction region overlaid.  There are about 2.5 million total counts from the SNR in this data set.

 Chandra image from a larger region that has been smoothed and contrast enhanced with the XIS extraction region overlaid to determine if there are any bright sources in the XIS extraction region: Image Added
Fit to the ACIS spectrum with the ESAC version 1.0 model for the 2.0-10.0 keV range.

Fit with the ESAC version v1.0 model in the 2.0-4.0 kV range looking for any missing lines, there do not appear to be any line features that the ACIS spectrum would require: Image Added

0.5-2 keV image of N132D from the XIS. The green box shows the FOV.

Suzaku/XIS1 full-band image with extraction region in magenta (left) compared to ACIS image and extraction region in green (right).

Suzaku/XIS spectra (black=XIS1, red=XIS0, green=XIS3) from 2010-07-27, with E212_v1.0_20110439.xcm model folded through. A constant normalization factor was allowed to vary for each XIS, but everything else was fixed. Norms are 1.27, 1.31, 1.28 (so ~30% larger than XMM model).

NICER XTI

NICER has ~21 ksec good data, taken between 2018-01-29 and 2018-02-23.  All 52 operating detectors were enabled.

Data were screened for undershoots in 0-40 ct/s/FPM range and overshoots in the 0-2 ct/s/FPM range, plus an additional cut on high energy X-ray counts (>2 keV, 0-4.5 ct/s/FPM cut).

This is a fit using the v2.11 model, only allowing the overall norm and NICER SCORPEON background terms to vary.

Image Added

The NICER norm is 0.993.  The backgrounds are pretty reasonable, although the "LEEL" background component would indicate a slightly rare condition.  Without "LEEL", the fit demands an additional high energy background component in the 2-10 keV range.

Using the v2.14 model, the NICER situation is considerable worse.

Image Added

NICER is not particularly sensitive to emission in the Fe K region.
