Medium Res Pinhole data

We took 14um Q-branch data while in medium res mode to evaluate the spatial and spectral focus while the echelle mirror was placed at different settings in the range of +8 turns to +15 turns. We used clickfit for all measurements. The images were 4SUTR, so we first made a single frame by subtracting frame4 from frame1 for each image. Then we rotated the images in IDL with the rotate(im,1) function. 

Then clickfit,/box was used on the region from point (200,500)--> (700,700), encompassing
most of the Q branch and some of the R-branch. We selected a sequence of 5 odd-numbered Q-branch lines to fit (something like 7-9-11-13-15, but I will determine this and update the post soon) and used these lines to fit 1-D Gaussians to. The tabular data below shows the median FWHM of the line fits and the standard deviation.
The plots show all measurements of the median FWHM values.

Once I identify the lines we used, I'll be able to get the pixel/wavelength scale and report the spectral resolutions.

It appears that +12 had the best spectral focus, and +11 was the best spatial focus.
