The Heilum wave cal data.

Below are my graphs of the helium 100ms data. The file contains 10 images of the helium lamp source. All the data are dark subtracted. See each graph below for more detail.

Track Wavelength fits:

Resonon took dark scans for the two int times taken. So I meaned all the dark images for the 100ms data and subtracted it from the data before processing. I Then took the 10 images and meaned them to get the surface plot below.

Figure 1

This is a cross section through the tracks at wavelength pixel 705, with one line for each of the 10 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 930.

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 135): The same surface plot but showing how individual helium peaks line up from track to track.

Figure 7

Helium Peak 2 (at pix 305): The same surface plot but showing how individual helium peaks line up from track to track.

Figure 8

Helium Peak 3 (at pix 461): The same surface plot but showing how individual helium peaks line up from track to track.

Figure 9

Helium Peak 4 (at pix 705): The same surface plot but showing how individual helium peaks line up from track to track.

Figure 10

Helium Peak 5 (at pix 930): 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.
