The knots will be identified froma WFC image to be line_3: obtained as an early acquisition exposure, line_4: as well as a scientific image. ! question: 4 section: 1 line_1: The ultraviolet is essential for key lines and the scattered continuum line_2: contributed by the higher scattering cross-section of dust grains in DQ Her's line_3: nebula. HST also provides the higher spatial resolution needed to resolve fine line_4: filamentary structure. ! question: 7 section: 1 line_1: Spectra as reduced by the standard STScI software will be analyzed at the line_2: University of Texas. WF/PC images will probably be handled at STScI. line_4: Interpretation will be integrated with our present work on DQ Her and related line_5: old novae. ! question: 10 section: 1 line_1: University and Departmental computing facilities. ! question: 13 section: 1 line_1: Ultraviolet spectra and images of the DQ Her's nebula will provide information line_2: on the gas and dust content of the cool ejecta from the 1934 outburst. ! !end of general form text general_form_address: lname: LAMBERT fname: DAVID mi: L. title: PROF. category: PI inst: UNIVERSITY OF TEXAS addr_1: ASTRONOMY DEPARTMENT addr_2: RLM 15.308 city: AUSTIN state: TX zip: 78712 country: USA phone: 512-471-7438 telex: 910-874-1351 ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: DQ-HER descr_1: A,152,161,917 pos_1: RA = 18H 06M 5.3S +/- .5S, pos_2: DEC = +45D 51' 01" +/- 2" equinox: 1950 pm_or_par: N fluxnum_1: 1 fluxval_1: V=14.2 fluxnum_2: 2 fluxval_2: SURF(6563)=4 +/- 2 E-16 fluxnum_3: 3 fluxval_3: W-LINE(6563)=1.0 +/- 0.2 ! targnum: 2 name_1: DQ-HER-A descr_1: A,152,161,917 pos_2: RA-OFF=-0.6S +/- 0.3S, pos_3: DEC-OFF= 8" +/- 4", pos_4: FROM 1 equinox: 1950 pm_or_par: N comment_1: TBD-EARLY FROM A WFC IMAGE TAKEN comment_2: IN A RELATED PROPOSAL comment_3: POSITION 2 CORRESPONDS TO LOCATION comment_4: A OF WILLIAMS ET AL.
