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 first data set is for the Lu tracks only, the second data set is for the Es, Ed and Lu data.

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. /

Data set 1 LuTop data and the darks and backgrounds taken before and after the data set. The darks and background vary quite a bit and both have sine waves in them. Some are also too high for the light scans. The temperature was stable at -40C during data collection so why are the darks changing so much with time? PS: the darks where taken closes in time to the lites so those will be used to subtract from the lites to get a net

Figure 3

Net signal for each Lu. By net I mean an average of the 5 lites for data set 1 and the 6 darks taken before and after the lites. These where each meaned and then subtracted from each other and divided by int time.

Data set 2 Es data and the darks and backgrounds taken before and after the data set. These are more stable because the ccd has been on longer??? I used the darks for subtraction on these data sets as well.
