GV Tau setting options

We looked at the flux per pixel in different order options for the 4 proposed medium mode settings of GV Tau in the next flight series: 1835cm-1 (5.45um), 1776cm-1 (5.63um),1745 cm-1 (5.73um)&1362cm-1 (7.34 um), 
The effect of groove shadowing on the flux is often so severe that I think we only have a single option in medium mode

Summary: 
1835cm-1  10th order      5.4278 - 5.4715  0.044 um
1776cm-1  10th order      5.6107 - 5.6507  0.04 um

1745cm-1  9th or 10th order 5.7039-5.7579, 0.054um or 5.7118-5.7496, 0.038um

1362cm-1  7th order       7.3073-7.3774, 0.07um
