The central arcsec will be well line_3: enough exposed to yield good-S/N spectra that are only 1 pixel line_4: (28 mas) high; farther out, successive rows will be averaged. The line_5: aim is to get a high-spatial-resolution rotation curve and also line_6: to get velocity dispersion as a function of position. line_8: Parallel WFPC2 exposures will yield population information at line_9: the edge of the bulge. ! ! end of abstract general_form_proposers: lname: KING fname: IVAN title: PROF. mi: R. inst: U.

The 6-hour exposure chosen should line_4: produce adequate S/N in a single pixel-column, within an arcsec line_5: of the center, and good S/N farther out when several columns are line_6: added together. ! question: 5 section: 1 line_1: Since the structures in the center of M31 are very small, the line_2: slit must be placed carefully. Therefore a Mode I acquisition is line_3: needed. ! !end of general form text general_form_address: lname: KING fname: IVAN mi: R. category: PI title: PROF. inst: U.
