- No spatial evidence for ‘patch’ found in N132D (larger remnant - more complex, spatially and spectrally - no thin-filter, on-boresight observations) - Other Objects? Coma – Many observations – All Medium Filter Tycho – 1 observation – Medium filter Kepler – 1 observation – Thick filter (No such features [spectral enhancements, spatial ‘patch’] seen in pn analysis - remnant however sometimes on CCD gap, or non-thin filter used)

- Fluxes calculated and compared (dotted lines show ±10% variation) 0.1-0.4 keV - Models (continuum + multi-Gaussian) fitted to spectra in narrow energy bands - Fluxes calculated and compared (dotted lines show ±10% variation) - On-Axis observations (433, 447, 894, 900) show marked departures from mean 0.4-0.8 keV 0.8-1.15 keV

- Zoom of 894-900 region (all on-axis)

- At higher energies, flux is very constant 1.15-2.0 keV - At higher energies, flux is very constant 2.0-6.0 keV - Across whole energy band, flux is quite well conserved 0.1-6.0 keV

Spatial Analysis of ‘Patch’ - Mosaic all ‘good’ off-axis sky (X/Y) images to obtain 0.1-0.35 keV images of ‘non-patch’ remnant - Using knowledge of remnant detector position and observation position angle, rotate and flip this image to correct RAWX/RAWY position & orientation for each ‘bad’ on-axis pointing - Subtract rotated/flipped image from each ‘bad’ on-axis RAWX/RAWY image (correcting for relative exposures) to obtain images of the remainder – the ‘patch’

- M1 patch is bright, and quite large already at rev 447 - Outer regions become larger and even brighter at later times

- M2 patch is not as bright as M1, and is initially compact - Outer regions become effected at later times

Mosaics (raw & smoothed) of ‘patch’ images for MOS1

Mosaics (raw & smoothed) of ‘patch’ images for MOS2

- Patch is only visible when remnant illuminates the particular area of detector - 1ES0102 acts like a torchlight – Final correction is made for this

New Boresights? MOS2 MOS1 Obvious places that are close, equidistant from pn/RGS boresights (and by pn-RGS boresight offset) and with relatively little photon impact

Discussion: Dealing with ‘The Patch’? – - New Boresight(s)? - Spatio-temporal RMF? - Correct on photon-by-photon basis?
