These are the track 7 laser data. The data have been divided by integration time and dark subtracted. I used SIRCUS_550_27 as the dark, I had to divide it by 10 because there were 10 accumulations so the dark counts were 10 times too high (ie 10 accumulations and 10 frames are not the same thing)

NOTE: I have changed the dark used on this data to the back1 file collected on 20 Nov 2009 The SIRCUS_550_27 file previusly used were higher than the light scans at the edges making them negative. All the "dark" scan collected during the laser work are higher than the light scans , they were also collected with 10 accumulations. Could this make them higher? Not sure but the back1 file makes the data look much more resonable.

I fixxed the two monitor voltages which were not correct for track 7 480 and 500 nm.
