New notes: The T column lists the approximate time in minutes for this line. This includes 5 minutes acquisition plus 1 minute for the comparison. The UT column is the approximate start time assumed for scheduling purposes. If you fall too far behind (say about 30 minutes), first drop priority 3 targets, then priority 2 targets. But don't worry if you are close to the strawman timeline. As I get experience with scheduling, I will try to make it more accurate. For now I am allotting the nominal overheads, plus 30 minutes for a change in the grating tilt/filter. -------------------------------------------------------------------- General Notes: Astronomical ephemerides are from SKYCAL, by John Thorstensen Pri: Target priority. 1 = observe object if possible 2 = extra targets; observe only if no Priority 1 target is available 3 = backup targets; low priority RA & Dec: all coordinates are accurate to 1"; charts can be generated by operator as necessary using LEDAS or DSS. Charts for many objects were prepared at telescope in February and should be available. The finding chart for RXJ0513 is in http://www.astro.sunysb.edu/fwalter/SMARTS/2003B/rxj0513.ps Finding charts for the SUNY 03b-02 program targets will be available soon. Cmp: 1 means take comparison spectrum only before target exposures; 2 means before and after ..............................................................................
