Part of an Email from Casey Smith on 7/1/2015 3:15 PM:
The "sphere" cube has all of the channels illuminated.  "Channel 7" is only 7, obviously.  Helium red and helium blue show the same 
helium discharge spectra at different integration levels in order to get data in the blue where the signal is weaker.

Casey send four bip files (channel7.bip helium blue.bip helium red.bip sphere.bip).

Below are my graphs of the channel7.bip file. The file contains 4 images of the white light source. Over all it looks really stable and track definition looks good. See each graph below for more detail.

I took the 4 images and meaned them to get the surface plot below. Note this still has the infrared artifact in it and you can see it around pixel 800.

Figure 1

This is a cross section through the tracks at wavelength pixel 900, with one line for each of the 4 images.

Figure 2

Same as the previous graph but zoomed into the bottom to see the level of the darks between the tracks.

Figure 3

Same as figure 2 but for Wavelength pixel 400.

Figure 4

Again this is the mean image with slices thought the image at different wavelength pixels.

Figure 5

Same as figure 5 but zoomed to the bottom so you can see the darks between the tracks.

Figure 6

Same as figure 6 but zoomed to the dark space to the left of track 7

Figure 7

All the tracks with track 7 being the only one with light on it.

Figure 8

Because there are no darks I subtracted the min value from each track and then ratioed each track to track 7 so get an idea of the cross track light
