    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

    Focal Plane Temperature

    Sep 2021 Focal Temperature

    The Mean (max) FPT:
    -111.57 +/- 4.72 C
    Mean Width:
    0.72 +/- 0.32 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.

    ACIS Rejected Events

    The links below are plots of stat1 quantities, showing on-board rejected events. The average EVTSENT, DROP_AMP, DROP_POS, DROP_GRD, THR_PIX, and maximum BERR_SUM obtained from L1 acis*stat1.fits files are plotted for each observation. CTI observations are plotted separately from regular science observations.

    Column definitions:

    Note the half-life decline of the CTI source is clearly evidenced in the steady janline of EVTSENT.

    ACIS Gain Trends

    We computed ACIS gain and offset from ACIS event1 files used in CTI computation, following the step described by C. Grant ACIS gain @ -120C page.

    Instead computing gains and offsets from individual observations, we combined all data from each month and computed an monthly averaged gain and offset.

    The following plots show CCD3 and CCD5 gains and offset trends.

    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.
