3. Check CCD cleaning

Finding: It turns out we have no control over CCD "cleanings" in this operational mode.

These graphs should check CCD cleaning. See excerpt from Tasks doc below.

NOTE: The OL420 was used for this cleaning data set (not the Hg Pen Lamp). The next day Zhigang moved the spec back to the Hg Pen Lamp and did the cleaning experiment again with the Hg Pen Lamp./

Tests 1 and 2 below should be done each time the setup is moved or significantly reconfigured, though in the future only one or two long integration time FDI scans would likely be required to confirm the absence of light leakage.

3. Check CCD cleaning

a. Source: He/Hg source(OL420 not Hg Pen), Light source on, all fibers illuminated Be sure to let the He / Hg source warm up
b. Adjust integration time for 55K ADU light signal at spectral peak
c. Image sequence for this test: 10 BI, 10LI, 10BI
d. Collect 1 image set at CCD cleaning settings 1,5,10 and Auto cleaning off and on for each setting (6 sets total)
e. Analysis

i. Look for residual light signal signature in the second set of darks.
