Track to Track stray light using the one_fiber data collected by Carol and Bob. Data is divided by int time and dark subtracted.

The frist set of graphs shows an artifact peak betweeen 390-400 nm (pixels 944-972), the peak shows up in the dark tracks between the peaks as well. At the end of this section is some images showing the tracks and were the atrifact peak is. This means (I think) the light is not coming from the fibers but from an internal reflection or something.

I created a second set of graphs which show and image of the atrifact peak and were it is in relation to the tracks.

Hi Mark,

I am still working on this ghost image problem.  I think it is a "double bounce" ghost reflection off of two refractive surfaces that then get imaged on the detector in the 0th order.  I will try to track down the culprits in the next day or two.

Each files data, note the extra peak about 400 nm (same place a laser 550 nm laser data)
