Additional Data Taking

  • Previously, plotted $\sigma_{\sigma}$ against exposure time for one spectral line from the Helium lamp
  • Noticed this plot was not smooth, and $\sigma_{\sigma}$ fluctuated quite significantly for different exposure time
Changed:

  • To try and smooth out this plot, we are taking 5 frames at each exposure time and finding the average error, rather than just analysing the one.
