Below are my graphs of the helium.bip file. The file contains 10 dark images. Note some graphs are dark corrected and some are not so check the axis labels to know what you are looking at.
Track Wavelength fits: P(1,:) = [1.285915e-05 0.3900751 507.9187] P(2,:) = [1.224339e-05 0.3904593 507.844] P(3,:) = [1.212312e-05 0.3904565 507.8696] P(4,:) = [1.171484e-05 0.3906984 507.8547] P(5,:) = [9.512546e-06 0.3921727 507.6411] P(6,:) = [1.207693e-05 0.3903579 507.9346] P(7,:) = [1.298784e-05 0.3898536 508.0375] P(8,:) = [1.224826e-05 0.3903056 507.9581] P(9,:) = [1.210826e-05 0.3904806 507.9298] P(10,:) = [1.211005e-05 0.3904454 507.9284] P(11,:) = [1.228684e-05 0.3904038 507.944] P(12,:) = [1.28729e-05 0.3901069 507.9767] P(13,:) = [1.258642e-05 0.3904429 507.924] P(14,:) = [1.342767e-05 0.3897316 508.0803]
Figure 1 I took the 10 images and meaned them to get the surface plot below.
Figure 2 This is a cross section through the tracks at wavelength pixel 501, with one line for each of the 10 images. The tracks and their shapes look really stable.
Figure 3 Same as the previous graph but zoomed into the bottom to see the level of the darks between the tracks.
Figure 4 Same as figure 2 but for Wavelength pixel 405.
Figure 5 Again this is the mean image with slices thought the image at different wavelength pixels. The pixels choosen are where the helium peaks are and +- pixel pixel around them.
Figure 6 Same as figure 5 but zoomed to the bottom so you can see the darks between the tracks.
Figure 7 Helium Peak 1 (at pix 203): The same surface plot but showing how individual helium peaks line up from track to track. Looks pretty good!
Figure 8 Helium Peak 2 (at pix 405): The same surface plot but showing how individual helium peaks line up from track to track. Looks pretty good!
Figure 9 Helium Peak 3 (at pix 501): The same surface plot but showing how individual helium peaks line up from track to track. Looks pretty good!
Figure 10 Helium Peak 4 (at pix 555): The same surface plot but showing how individual helium peaks line up from track to track. Looks pretty good!
Figure 11 Mean image binned by track, the x-axis is wavelength pixels.
Figure 12 Close up of one of the helium peaks
Figure 13 Close up of one of the helium peaks
Figure 14 Close up of one of the helium peaks
Figure 15 Close up of one of the helium peaks
Figure 16 MY VERY ROUGH GUESS AT A WAVELENGTH CAL!!! THIS ASSUMES I GUESS CORRECTLY WHICH PEAKS WHERE WHICH HELIUM LINES. Originally I had ~ 506.51, 921.42, but after Mikes email I drop the peak at 683 and changed from 2nd order to linear. Mikes says "pix #1 = 504.70, pix #1024 = 911.97, with pixel separation = 0.40 nm"
