In afternoon or during dinner: - Install 56/II grating setup - CONFIRM THAT THE GRATING TILT IS SET TO EXACTLY 22.90 - check focus - obtain at least 10 Zero frames - obtain at least 5, preferably 10, flat-field frames (projector or dome) Try to get a few good twilight spectra at the beginning (or end) of the night, but only if it would not interfere with observations of target stars. SPECIAL NOTES: NOTE: Don't observe any target at airmass > 2.0, and preferably no higher than ~1.8. Just skip them, since the spectra won't be useful anyway. Make sure to observe the 1+ targets. During the rest of the night, select targets according to the listed priorities. There are more targets than can be observed. If you find that there are not enough good targets available at any time during the night, you can make the exposures longer for the targets that ARE available. Making them 2 or 3 times longer will not cause most of them to saturate.

Charts for many objects were prepared at telescope in February 2003 and should be available. Cmp: 1 means take comparison spectrum only before target exposures; 2 means before and after
