Figure 1: Filter wheel closed spectra for the MOS1 ( upper) and MOS2 ( lower) detectors. The MOS2 data have been scaled by a factor of 1.5 in order to separate the spectra for clarity. The spectra are comprised of a general continuum from the QPB and the FX lines of Al, Si, Au, and other elements. The energy binning for the data is a constant 15 eV. |

Figure 3: Top panel: QPB count rate in the 0.3-10.0 keV band from the out-of-FOV corners of the detectors from KS07 (their Fig. 6) for the individual CCDs from both MOS instruments. The MOS1 data are shown in black, the MOS2 data are shown in blue, and time periods of anomalous CCD background behavior are shown in red. Bottom panel: QPB (2.5-5.0 keV)/(0.4-0.8 keV) hardness from the out-of-FOV corners of the detectors from KS07 (their Fig. 7) for the individual CCDs from both MOS instruments. The MOS1 data are shown in black, the MOS2 data are shown in blue, and time periods of anomalous CCD background behavior are shown in red. The plot limits are 0-0.075 counts s-1 chip-1 for the count-rate plots and 0-7.5 for the ratio plots. The data are linearly scaled in both cases. |

Figure 4: Image in detector coordinates of the SP data for the MOS1 ( upper row) and MOS2 ( lower row) detectors. From left to right the data are from the 0.35-0.8 keV, 0.8-1.25 keV, 1.25-2.0 keV, 2.0-4.0 keV, and 4.0-8.0 keV bands. In the plots blue and green indicate lower intensities while red and white indicate higher intensities. The data are linearly scaled. For better statistics, data are from the observations using all filters have been combined as there is little difference between the distributions for the thin, medium, and thick filter observations separately. Note that the distributions are not flat across the detectors nor are they symmetrically vignetted like cosmic X-rays. As well, the distributions are not the same for different energies. |

Figure 5: Sample light curves and light-curve histograms from two observations with different amounts of SP contamination. The top two panels show the light-curve histogram and light curve for the data from ObsID 0202130101 while the bottom two panels show the same for ObsID 0049150101. |

Figure 6: Spectra from two of the four XMM-Newton EPIC MOS observations of the Hubble Deep Field North (ObsID 0202130101 in black and ObsID 0049150101 in red). The black data points and curve show the spectrum from the contaminated observation while the red data points and curve show an uncontaminated spectrum. The uncontaminated spectrum agreed well with the two other observations of this direction. The additional curves show the fitted model contributions to the fits where all components besides the SWCX emission were fit simultaneously for the two spectra. |

Figure 8: Temporal filtering results for the MOS1 Abell 1795 cluster observation with ObsID 0097820101. The upper panel plots the light curve histogram for the 2.5-12.0 keV band from the FOV, the middle panel displays the 2.5-12.0 keV band FOV light curve, and the lower panel displays 2.5-12.0 keV band light curve from the unexposed corners of the instrument. The histogram is derived from the smoothed light curve. In the upper panel, the blue vertical lines show the range for the Gaussian fit, the green curve shows the Gaussian fit, while the red vertical lines show the upper and lower bounds for filtering the data. In the bottom two panels green points indicate accepted data while black points indicate data excluded by the filtering algorithm. The high count rate excursions are produced by soft protons rather than a particle background flare as the latter case would produce a similar increase in the corner data. |

Figure 9: Spectra from two annuli from the Abell 1795 analysis, 1'-2' ( upper panel) and 10'-15' ( lower panel). In each panel the upper spectrum is the total spectrum while the lower spectrum is the modeled QPB spectrum. The data have not been normalized for solid angle, otherwise the 1'-2' spectrum would be relatively brighter by about two orders of magnitude. |

Figure 10: Spectral fit to the data from Abell 1795. MOS1 and MOS2 spectra are shown for all ten annuli, as well as the ROSAT spectral energy distribution. The lower panel shows the ratio of the data to the model and demonstrates that the fit is reasonably good over the full dynamic range. |

Figure 16: The two plots display the comparison results from using Anders & Grevesse (1989) and Lodders (2003) abundances for the fitted values of the abundance ( upper panel) and temperature ( lower panel). In the upper plot the line is the best-fit scale factor of 1.44 while in the lower plot the line shows the one-to-one relationship. In both plots the filled circles indicate data from the outer annuli. |

Figure 17: Comparison of the fitted values for the annuli iron abundances and emission temperatures using Anders & Grevesse (1989) and Lodders (2003) model abundances while allowing all abundances to vary. The upper panel shows the correlation between the fitted values for the iron abundance for the two abundance models. The solid line is the best-fit correlation of 1.47 while the dashed line shows the 1.44 correlation of the single abundance normalization. The lower panel shows the fitted values for the temperatures where (open circle) abundances starting with Anders & Grevesse (1989) values were allowed to vary independently, (filled circle) Anders & Grevesse (1989) values were allowed to vary only with a single scale factor, and (filled triangle) Lodders (2003) values were allowed to vary only with a single scale factor. |
