- 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)

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

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 1
Mosaics (raw & smoothed) of patch images for 2
- 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? 2 1 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?
