Mike tooks some laser data with all tracks on to get a approximate wavelength cal and get a first look at the stray light of the red spec. I found the pixel for each track and wavelength three ways. The simplest was to just find the maximum value for the track (this does not take into account that the wavelength may not be centered on the pixel. The second two ways are using Gausiann fitting programs: mygaussfit and gaussfit. They where downloaded from the Matlab userfiles so not guarantees of how they work. This should find a truier center pixel for the laser data. One other issue is how accurate the laser wavelengths are.
All the graphs just shows the data the track listing in the title or legend. The secondset of graphs shows the laser data taken and is zoomed in on the peaks. The last three shows the relationship between the Laser wavelength and its pixel for the three ways to get the laser pixels. A second order polynomial was used and I liked the laser peaks from the mygaussfit programs so that was the one I used create the wavelength cal. The bottom of the page is a listing of the tracks, laser wavelength and laser pixels used in the polynomial fits.
