No optical light from SCHP

We tried to see if we could get light from the SCHP, set at temperatures of 23C, 100C and 200C.

We set the ctdelay to 150 (exptime=4s) and took 16 coadded frames, and repeated for 10 images for each setting.

All images were taken in imaging mode or pupil imaging mode; echelle at face-on, echelon bypassed, slit/decker/filter OPEN.

In B_12_07_25/

b000
b001-b010, T=23C, imaging mode
b011-b020, T=100C, imaging mode
b021-b030, T=100C, pupil imaging (25.4mm KRS5 lens)
b031-b040, T=200C, pupil imaging (25.4mm KRS5 lens)
b041-b050, T=200C, imaging mode

Taking only good pixel values (between 8125 and 10625 for coadded frames / 16.0)
We get:

Setting                          mean pixel value +/- stddev(pixel value)
T=23 C , imaging        9243 +/- 3
T=100 C, imaging       9244 +/- 3
T=100 C, pupil            9245 +/- 3
T=200 C, pupil            9244 +/- 3
T=200 C, imaging       9242 +/- 3
