    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

    January 2010 Focal Temperature

    The Mean (max) FPT:
    -111.61 +/- 6.35 C
    Mean Width:
    0.42 +/- 0.38 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.

    Bad Pixels

    The plots below were generated with a new warm pixel finding script. Please see Acis Bad Pixel Page for details.

    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.

    NOTE:

    Many sources observed during December had very high dose, and could not be used to compute science instrument background rates. Consequently, the plots for December are very spersely ploted.



    ACIS Corner Pixels

    We plot the average corner pixel centroid slope and mean for ACIS observations. Separate plots are shown for FAINT MODE (3X3) and VFAINT MODE (5X5) observations. Metric is the centroid of a Gaussian fit to the histogram of corner pixel PHA values of detected events. Plus signs are FAINT observations, diamonds are VFAINT observations, and boxes are VFAINT observations with centroids computed using only the corner pixels of a 3X3 event island (referred to as AFAINT). We see a very small upward trend.

    ACIS Bias Trends

    The bias plus overclock level was calculated as follows:

    CCDS 0, 2 and 8 are the most extreme.

    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 Focus pages. (NOTE: the figures are not updated from Mar 2009 due to a system problem.)
