The files below are the darks and background collected during the lastest in-water tests, these are from an automated program . Darks and backgrounds where collected in groups of 3. 3 backgrounds, 3 dark, 5 lites (not shown), 3 dark and 3 backgrounds and then the process is repeated a second time. See the file numbering below.

The files I am calling darks where taken with the camera shutter closed and external shutter open. Backgournd files where collected with the camera shutter open and the external shutters closed. /

The first graph is the track 7 darks for all the files. The second is the track 7 backgrounds. All are in ADU. Figues 3-6 are the dark pixels for 3 pixels on the array. One line is the wavelength direction and the other is the track direction. The 7th graph is the track 7 mean for all the files against time. So you can see how long it is between data collections and any decrease in darks with time. The 8th graph is the darks and backgrounds in ADU data verse int time. The 9th graph is the same ADU data but this time divided by int time. The final set of graphs shows the first 3 dark or background images for each of the repeats Art did.
