    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

    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.

    Gratings

    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.


    Gratings Resolving Power

    We plot E/dE vs. E for fits to detected lines with fwhm_error/fwhm less than 0.15 for the plus and minus arms of HEG, MEG, and LEG. Also shown are conservative (dotted line) and optimistic (dashed line) pre-launch resolving power expectations.

    We have selected only calibration observations of Capella, HR1099, and Sigma Gem. See MIT technotes for a parallel analysis.

    Plot symbol indicates dispersion arm: Color indicates observation date:
      Plus side = plus (+)
      Minus side = cross (x)

    SIM Shift and Twist

    SIM Shift and Twist Trend The following plots show trends of SIM shifts (dy and dz) and twist (dtheta). All quantities are directly taken from pcaf*_asol1.fits files. The units are mm for dy and dz, and degree for dtheta. We fit three lines separated before and after (Days of Mission)= 1400 (May 21, 2003), 2700 (Dec 11, 2006), and 4400 (Aug 07, 2011). The unit of slopes are mm per day or degree per day.

    The sudden shift around DOM = 1400, 2700 and 4400 are due to fid light drift (see a memo by Aldcroft fiducial light drift). On the dtheta plot, two tracks are clearly observed. The track around 0.01 is due to HRC-I, and all others are clustered around -0.002. For more detail, please see SIM Shift and Twist Trend page
