I used the merged Track 7 data to create a SPR. This is the matrix which will be used to straylgith correct the Track 7 data. I have ignored and artifact peak issues or any other features. This is just a linear interpolation of the laser data to fill in the missing laser peaks. Any data less than 1e-7 was set to zero (seen as white areas in the images.

I chose the in-band area to be plus or minus 5 pixels from the peak.

See Experitment 7.2 and notes on 21 Feb for changes to the matrix.
