Medium Resolution Pinholes CD015

 Medium resolution mode spectra of C2H2 Q-branch at ~55.6 deg echelle angle.

Best spectral:  12 T around column 600-800
Best spatial: 9T around column 600-900
Roundness: 10-11T around column 600-800



Rinse subtracted data; using slit wheel pinhole only; pinhole spectra are stacked with y-offsets.
