Statler CoI_Institution: University of North Carolina Contact: Abstract: Spectra from 3600-5400A will be taken with the FOC long-slit spectrograph laid across the two central brightness peaks of M31, to study the rotational velocity and the velocity dispersion as a function of position. The central arcsec will be well enough exposed to yield good-S/N spectra that are only 1 pixel (28 mas) high; farther out, successive rows will be averaged. The aim is to get a high-spatial-resolution rotation curve and also to get velocity dispersion as a function of position. Parallel WFPC2 exposures will yield population information at the edge of the bulge. Questions ! Free format text (clear and concise) Observing_Description: The first two orbits are for acquisition, with an uplink of a positional correction at the end of each. The next 7 orbits are used to accumulate enough counts for a good S/N. The parallel exposures are for colors and magnitudes of the faint blue stars that are responsible for the UV upturn. The required orientation is nominal around November 26. (The orientation 180D away can be reached only during the SAZ.) Note also the request that the parallels be lengthened by hand if the primaries are expanded (since RPS2 will not accept EXPAND on parallels). Note that no parallels are included in the last two orbits since they will not schedule then and thus prevent the primaries from scheduling if the parallels are included. Real_Time_Justification: An acquisition orbit is needed to position the slit exactly right. Calibration_Justification: N. A. Additional_Comments: The whole program can be taken on a single GSACQ. It can be scheduled only in late November. Parallels are commented out pending availability of an RPS2 that can process them. This is an FOC/48 program and will run only if that mode proves viable. The PC know that this is a 9-orbit visit and believes it is OK. See visit-level comment. Fixed_Targets !
