Subject: Runs night + morning shifts 16.04. 
Runs of the night shift 16.04. after changing the wavelength range. The new range is 320.12 - 319.859 nm. The step size was decreased from 0.002 nm to 0.001 nm.
The goal was to have the same number of scans as before (261), however, the scan range in the labview program could not be set accordingly. We decided to go with 262 scans after the first run.
