Are the main sources line_2: of ionizing radiation nonthermal, or due to a blue stellar population? High line_3: spatial resolution of ST is essential to this problem; FOS spectra can line_4: distinguish between a population of hot young stars or HB stars. Use the 0.3" line_5: aperture at any central point sources and off nucleus at the appropriate spot line_6: determined from WFPC data. Choose this spot within 1", along the major axis in line_7: accord with the techniques of FOS program 24, "Dynamics near Cores of Normal line_8: Galaxies." ! ! end of abstract general_form_proposers: lname: BEAVER fname: EDWARD inst: UC, SAN DIEGO country: USA ! lname: BURBIDGE fname: E.

The total line_4: exposure time for the CR-SPLIT exposure through the F656N line_5: filter should be 3600s, and the total exposure time for the line_6: CR-SPLIT exposure through the F547M filter should be 1200s. line_7: The F656N and F547M exposures should have a CR-SPLIT of 0.5. line_8: All exposures should be obtained at the same spacecraft line_9: position and roll angle, and should be scheduled GROUP NO line_10: GAP.
