Day2 Lu system response using the OL425(L9) W6D100 - 6 inch distance between the sphere and Lu head. The PD monitor fL values = not yet.

Mikes Lu system response data for LuTop, LuMid and LuBot on the BS03 after the Lu Heads are on, shutters in place and the iris adjusted.

5 lites and 5 backgrounds meaned for each Lu Track

Figure 1

Net signal (ADU/pix/sec) - dark subtracted - adjusted by 0.9894. No fL normalization currently.

Figure 2

Net signals divided by the MOBY261 LuTop cal lamp data (interpolated to BS01 wavelengths)

Figure 3

Trying to figure out exposure times. I multiplied Mikes Lu response by a in-water (good) LuTop, Mid or Bot data set and got the below graph for each Track. I think the units are now ADU/pix/sec. So what int time will get the data to 50K. The below table shows the max int time for each Lu track, if I did my math right. The are very similar to the one calculated from the rough cal on day 3.

Trk  Max ADU   Exposure to get 50K ADU 
 9      6729        7.4 
11      3880       12.8
13      5150        9.7
