    The Mean Detrended CTI

    We report CTIs with a refined data definition. CTIs were computed for the temperature dependency corrected data. Please see CTI page for detailed explanation. CTI's are computed for Mn K alpha, and defined as slope/intercept x10^4 of row # vs ADU. Data file: here

    The Mean (max) FPT:
    -112.31 +/- 3.58 C
    Mean Width:
    0.87 +/- 0.4 days

    Averaged Focal Plane Temperature

    We are using 10 period moving averages to show trends of peak temperatures and peak widths. Note, the gaps in the width plot are due to missing/corrupted data.

    This page shows scientific instrument background data based on Acis observations. A source region file is generated using get_srcregions and then the input event file is filtered using the regions in that file to remove the sources.

    HRMA Focus

    Plots below show various characteristics of detected imaging sources. Standard level 2 data products (*src2.fits) are used. Only observations with focus (sim_x) within 0.01 mm of nominal value for given SI configuration are used. Sources are also filtered for strength (SNR > 15).

    Grating Trends/Focus

    We plot the width of the zero order streak of ACIS/HETG observations and the width of the zero order image for HRC/LETG observations of point sources. No significant defocusing trend is seen at this time. See Gratings Trends pages.
