THE SPATIAL RESOLUTION OF HST WILL PERMIT US TO line_4: OBTAIN SPECTRA OF INDIVIDUAL KNOTS HAVING VERY DIFFERENT OPTICAL line_5: CHARACTERISTICS THAT ARE BLENDED TOGETHER IN SPECTRA OBTAINED WITH line_6: IUE. THE OPTICAL DATA WITH THE SAME APERTURES IN THE SAME POSITIONS line_7: WILL ENSURE A PROPER UV/OPTICAL COMPARISON. THESE DATA WILL PROVIDE line_8: IMPORTANT DIAGNOSTICS OF THE EXCITATION MECHANISMS IN THIS OBJECT line_9: AS WELL AS TESTS OF NUCLEOSYNTHESIS THEORIES FOR MASSIVE STARS, AND line_10: WILL PERMIT AN IMPROVED UNDERSTANDING OF THE DYNAMICS OF SN EXPLOSIONS line_11: AND MIXING IN THE EJECTA. ! ! end of abstract general_form_proposers: lname: BLAIR fname: WILLIAM title: PI mi: P. inst: JOHNS HOPKINS UNIVERSITY country: USA ! lname: KIRSHNER fname: ROBERT mi: P. inst: HARVARD UNIVERSITY country: USA ! lname: WINKLER fname: P.

This is the best compromise between line_4: desired spatial resolution and throughput. Furthermore, line_5: the paired aperture is not being used for "sky line_6: subtraction" but simply for its larger throughput. Hence, line_7: STEP-PATT=SINGLE has been set as an optional parameter. line_8: Since the filaments being observed are extended at the line_9: several arcsec level, we will be able to blind offset from line_10: a nearby GSSS star with relative impunity. A line_11: mis-positioning even by as much as 0.5-1.0" is not line_12: critical, although hopefully it will be better than that. line_13: We assume a filled 1" square aperture and no PSF light line_14: loss as would be the case for a point source. We assume line_15: exposures with FOS/BL G160L (3800s), and FOS/RD G270H line_16: (1700s), G400H (800s), and G570H (800s) at each of the two line_17: positions. G160L is considerably lower resolution than line_18: the other gratings, but covers the FUV range of interest line_19: with one grating. Even so, the G160L resolution should be line_20: superior to that achieved with IUE (~11A). Combined line_21: UV/optical data are requested with the same apertures in line_22: the same positions to avoid comparing "apples and line_23: oranges". The switch from FOS/BL to FOS/RD (or vice ! question: 3 section: 2 line_1: versa) can be accomplished at each position without line_2: re-acquiring the offset star, implying that the line_3: observations need to be done as a block (i.e. without line_4: other observations interspersed). The ordering of the line_5: gratings, however, is not important and can be done so as line_6: to make the observation as efficient as possible. As line_7: shown in section 4 below, these exposures will provide line_8: excellent detections of known UV/optical lines as well as line_9: permitting a search for possible fainter features that line_10: might be present at hitherto undetectable levels. ! !end of general form text general_form_address: lname: BLAIR fname: WILLIAM mi: P. category: PI inst: Johns Hopkins University addr_1: 237 BLOOMBERG CENTER addr_2: DEPARTMENT OF PHYSICS AND ASTRONOMY addr_3: JOHNS HOPKINS UNIVERSITY city: BALTIMORE state: MD zip: 21218 country: USA phone: 410-516-8447 ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: STAR1-OFFSET descr_1: J,707 pos_1: RA = 05H 24M 44.47S +/- 0.5", pos_2: DEC = -69D 37' 48.4" +/- 0.5" equinox: 2000 comment_1: OFFSET STAR FOR USE WITH N132D comment_2: CHOSEN FROM HST GUIDE STAR CATALOG fluxnum_1: 1 fluxval_1: V=11.8 +/- 0.3 ! targnum: 2 name_1: N132D-POS1 descr_1: H,506 pos_1: RA = 05H 25M 05.57S +/- 1", pos_2: DEC = -69D 38' 11.8" +/- 1" equinox: 2000 comment_1: S-RICH SNR FILAMENT IN LMC comment_2: SUPERNOVA REMNANT N132D fluxnum_1: 1 fluxval_1: SURF(1549) = 2.8 +/- 0.5 E-15, ! targnum: 3 name_1: N132D-POS2 descr_1: H,506 pos_1: RA = 05H 25M 05.65S +/- 1", pos_2: DEC = -69D 38' 15.8" +/- 1" equinox: 2000 comment_1: O-RICH SNR FILAMENT IN LMC comment_2: SUPERNOVA REMNANT N132D fluxnum_1: 1 fluxval_1: SURF(1549) = 2.6 +/- 0.5 E-15, ! ! end of fixed targets !
