An oxygen-rich SNR in NGC 4449 line_7: will be observed, taking advantage of the small FOS slits to isolate the SNR line_8: from surrounding H II emission. Two M33 SNRs that were previously part of this line_9: proposal have been dropped due to time limitations. line_10: This proposal is augmented time to obtain early acq images of two LMC remnants line_11: and spectra of N49, which had early acq images in Cy. 0. line_12: NOTE: SPECTROSCOPY AND IMAGING ORIGINALLY IN THIS CYCLE 2 PROPOSAL HAVE BEEN line_13: SPLIT BY STSCI INTO TWO SEPARATE PROPOSALS TO ALLOW FOR SCHEDULING OF CYCLE 2 line_14: EARLY ACQ IMAGING ( FOR LATER CYCLES ) SINCE CYCLE 2 SPECTROSCOPY DEPENDS ON line_15: MEASUREMENT OF EARLY ACQ IMAGING OF OTHER TARGETS FROM EARLIER CYCLES. ! ! end of abstract general_form_proposers: lname: BEAVER fname: EDWARD inst: UC, SAN DIEGO country: USA ! lname: BURBIDGE fname: E.

It will be necessary, therefore, to obtain short WFC line_3: exposures to permit exact positions for the FOS aperture to be chosen. The line_4: slit positions relative to offset stars (also chosen from the WFC images) will line_5: be measured and the FOS will be positioned by blind offset. A similar technique line_6: will be used to place a smaller FOS slit on the SNR in NGC4449. line_10: Each object will be observed with a sequence of gratings providing coverage line_11: from 1150-6800 A (thus overlapping with existing optical data). line_13: NOTE: SPECTROSCOPY AND IMAGING ORIGINALLY IN THIS CYCLE 2 PROPOSAL HAVE BEEN line_14: SPLIT BY STSCI INTO TWO SEPARATE PROPOSALS TO ALLOW FOR SCHEDULING OF CYCLE 2 line_15: EARLY ACQ IMAGING ( FOR LATER CYCLES ) SINCE CYCLE 2 SPECTROSCOPY DEPENDS ON line_16: MEASUREMENT OF EARLY ACQ IMAGING OF OTHER TARGETS FROM EARLIER CYCLES. ! question: 5 section: 1 line_1: The SV prerequisite programs for all FOS observations in this line_2: program are: line_3: Prop ID 2195 FOS Target Acquisition Tests All observations line_4: Prop ID 1317 Int./Ext.

The other objects are interesting each in their own right, and line_4: while comparison of one object to another will be useful, the observations of line_5: each object define a viable investigation. ! question: 13 section: 1 line_1: UV and optical spectra of four extragalactic supernova remnants will be line_2: used to study a number of problems relating to abundances, interstellar medium line_3: properties, nucleosynthesis, grain destruction and physical conditions in the line_4: remnant shocks. Observations will be concentrated in the LMC, although line_5: the oxygen-rich remnant in NGC 4449 will also be observed. ! !end of general form text general_form_address: lname: DAVIDSEN fname: ARTHUR mi: F. category: PI inst: JOHNS HOPKINS UNIVERSITY addr_1: CENTER FOR ASTROPHYSICAL SCIENCES city: BALTIMORE state: MD zip: 21218 country: USA ! ! end of general_form_address records fixed_targets: targnum: 4 name_1: STAR1-OFFSET descr_1: J,707 pos_1: RA = 05H 26M 10.91S +/- 0.05S, pos_2: DEC = -66D 06' 03.63" +/- 1" equinox: 2000 comment_1: UPDATE FOR WFC DISTORTION HAS comment_2: BEEN INCLUDED IN SPECIFIED comment_3: COORDINATES. fluxnum_1: 1 fluxval_1: V=16.5 +/- 0.3 ! targnum: 11 name_1: N49-P1 descr_1: H,506 pos_1: RA-OFF =6.04S +/- 0.01S, pos_2: DEC-OFF =57.10" +/- 0.2", pos_3: FROM 4 comment_1: UPDATE FOR WFC DISTORTION HAS comment_2: BEEN INCLUDED IN SPECIFIED comment_3: OFFSETS. fluxnum_1: 1 fluxval_1: F-LINE(1550)=8.4 +/- 2.0 E-16, fluxval_2: W-LINE(1550)=1 fluxnum_3: 2 fluxval_3: E(B-V) = 0.05 ! ! end of fixed targets !
