Mike tooks some laser data with all tracks on to get a approximate wavelength cal. The main purpose of this data are to get a data set before the instrument is shipped to Miami. This way when it gets back we can check the effects of shipping.
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 show all 14 tracks. 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.
2nd order polynomial regressions coeff for each track P(1,:) = [1.31536e-05 0.336041 339.666 ]; P(2,:) = [1.29301e-05 0.336209 339.644 ]; P(3,:) = [1.28961e-05 0.336238 339.633 ]; P(4,:) = [1.33192e-05 0.335806 339.712 ]; P(5,:) = [1.33509e-05 0.33574 339.746 ]; P(6,:) = [1.34118e-05 0.335674 339.787 ]; P(7,:) = [1.34743e-05 0.335617 339.812 ]; P(8,:) = [1.34956e-05 0.335634 339.746 ]; P(9,:) = [1.3322e-05 0.335829 339.729 ]; P(10,:) = [1.35407e-05 0.335635 339.726 ]; P(11,:) = [1.36746e-05 0.335553 339.709 ]; P(12,:) = [1.34161e-05 0.335794 339.67 ]; P(13,:) = [1.35678e-05 0.335735 339.632 ]; P(14,:) = [1.36357e-05 0.335685 339.613 ]; Min and Max wavelengths for each track Track 1 [min/max nm] = [340.002 697.565 ]; Track 2 [min/max nm] = [339.98 697.48 ]; Track 3 [min/max nm] = [339.969 697.464 ]; Track 4 [min/max nm] = [340.048 697.544 ]; Track 5 [min/max nm] = [340.082 697.543 ]; Track 6 [min/max nm] = [340.123 697.581 ]; Track 7 [min/max nm] = [340.148 697.613 ]; Track 8 [min/max nm] = [340.082 697.587 ]; Track 9 [min/max nm] = [340.065 697.587 ]; Track 10 [min/max nm] = [340.061 697.615 ]; Track 11 [min/max nm] = [340.045 697.655 ]; Track 12 [min/max nm] = [340.006 697.591 ]; Track 13 [min/max nm] = [339.968 697.651 ]; Track 14 [min/max nm] = [339.948 697.652 ];
