Use the 0.9" slit and the high dispersion B1200 grating centered at 4280A. This gives me 3660A to 4900A (1240A total range). If I have more time at the very end maybe put in the B400 grating and just re-observe everything. Shorter exposure times and would give me some coverage of TiO bands.
Sunrise is at 5:56. Astronomical twilight ends at 4:14. Civil twilight ends at 5:27.
If I assume the exposure times in the table (calculated using B magnitudes and the exposure time calculator) and then assume a 5 minute overhead, the 68 targets can be observed in 17 hours. If I multiply the exposure times by 5, it takes 63 hours. If I multiply by 10, it takes 121 hours.
If I take out the non-HL targets (9 of them ... mostly really faint), then given the criteria above I get 5.5 hours, 8 hours and 11 hours.
Arcs - He and Ar are good in the UV / blue. According to the manual section 4.2, the exposure time should be somewhere between 60 and 120s. I only need a few of these in the afternoon since I'm not doing radial velocities.
Flats - I want the S/N in the blue to be around 500. This will require a lot of flats. The maximum exposure is around 960s so every afternoon take maybe three or four 600s flats.
Standards - There is already a standards catalog here.
Parallactic Angle - calculate using sky calc. Input file with numbers. From website: "Again, remember that the commanded position angle needs to be set at 90 degrees from the desired parallactic angle!"
