The Heilum wave cal data.

Below are my graphs of the helium data. The file contains 20 images of the helium lamp source. All the data are dark subtracted. See each graph below for more detail.

Track Wavelength fits:
P(1,:) = [1.174133e-05     0.3391097       337.526]
P(2,:) = [1.04971e-05     0.3407219       337.056]
P(3,:) = [1.060547e-05     0.3405821      337.0923]
P(4,:) = [1.18615e-05     0.3388069      337.6627]
P(5,:) = [1.102403e-05     0.3399423      337.3048]
P(6,:) = [1.109827e-05     0.3398238      337.3877]
P(7,:) = [1.127505e-05     0.3396121      337.4563]
P(8,:) = [1.077157e-05     0.3401986      337.2839]
P(9,:) = [1.010149e-05     0.3410878      337.0654]
P(10,:) = [1.039405e-05     0.3407349      337.1147]
P(11,:) = [1.076068e-05     0.3403096      337.2514]
P(12,:) = [1.159738e-05     0.3391895      337.5441]
P(13,:) = [1.168309e-05     0.3391254      337.5974]
P(14,:) = [1.14926e-05     0.3394194      337.4877]

I Then took the 20 images and meaned them to get the surface plot below.

Figure 1

This is a cross section through the tracks at wavelength pixel 719, with one line for each of the 20 images. The tracks and their shapes look really stable.

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 944.

Figure 4

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 5

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

Figure 6

Helium Peak 1 (at pix 151): The same surface plot but showing how individual helium peaks line up from track to track.

Figure 7

Helium Peak 2 (at pix 321): The same surface plot but showing how individual helium peaks line up from track to track.

Figure 8

Helium Peak 3 (at pix 476): The same surface plot but showing how individual helium peaks line up from track to track.

Figure 9

Helium Peak 4 (at pix 719): The same surface plot but showing how individual helium peaks line up from track to track.

Figure 10

Helium Peak 5 (at pix 944): The same surface plot but showing how individual helium peaks line up from track to track.

Figure 11

Mean image binned by track, the x-axis is wavelength pixels.

MY VERY ROUGH GUESS AT A WAVELENGTH CAL!!! THIS ASSUMES I GUESS CORRECTLY WHICH PEAKS WHERE WHICH HELIUM LINES.
