    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

    Jun 2023 Focal Temperature

    The Mean (max) FPT:
    -109.6 +/- 6.14 C
    Mean Width:
    0.6 +/- 0.24 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.

    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.

    Fid Light Drift

    Fid light positions on ACA drift with time. The drift trends of Fid light 2 with ACIS-I and ACIS-S configurations are shown below.

    The top panel shows Fid light 2 drift in ACENT I (app. along with -Y axis), and the bottom panel shows that in ACENT J (app. along with Z axis). The unit is a pixel, and one pixel is approximately 0.5 arcsec. The slope listed at the top right corner is the change in a position per year (arcsec/yr). The vertical line on DOM = 1411 (Jun 1, 2003) indicates a transition date of use of IRU-1 to IRU-2.
