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. ! ! 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). ! 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. Wavelength Offsets 1st target line_5: Prop ID 1318 Spectral Flat Fields 1st target line_6: Prop ID 1320 Absolute Spectrophotometry 1st visit of line_7: bright targets ! question: 12 section: 1 line_1: The two M33 SNRs that have previously been part of this proposal have been line_2: dropped from the program due to the time limitations incurred because of the line_3: PSF problem. 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: 7 name_1: STAR4-OFFSET descr_1: J,707 pos_1: RA = 12H 28M 06.38S +/- 0.1S, pos_2: DEC = +44D 05' 54.97" +/- 1" equinox: 2000 comment_1: UPDATE FOR WFC DISTORTION HAS comment_2: BEEN INCLUDED. fluxnum_1: 1 fluxval_1: V=17.0 +/- 0.3 ! targnum: 17 name_1: NGC4449-SNRP1 descr_1: H,506 pos_1: RA-OFF= 4.535S +/- 0.01S, pos_2: DEC-OFF= 53.63" +/- 0.1" , pos_3: FROM 7 equinox: 1950 comment_1: UPDATE FOR WFC DISTORTION HAS comment_2: BEEN INCLUDED. fluxnum_1: 1 fluxval_1: F-LINE(5007)=1.3 +/- 0.3 E-15, fluxval_2: W-LINE(5007)= 110 +/- 5 ! ! end of fixed targets !
