Our aim is to continue our line_3: optical and ultraviolet studies of NGC 1068 using the much higher angular line_4: resolution available with the FOC. The main fields of interest are: the line_5: massive burst of star formation which takes place in the inner spiral arms and line_6: the high ionization emission line gas in between and around these arms and the line_7: energy supply of this high ionization gas far away from the nucleus. ! ! end of abstract general_form_proposers: lname: BOKSENBERG fname: ALEC inst: ROYAL GREENWICH OBSERVATORY country: UNITED KINGDOM esa: X ! lname: SNIJDERS fname: TOON inst: ASTRONOMISCHES INSTITUTE, TUBINGEN country: WEST GERMANY esa: X ! lname: SNIJDERS fname: TOON inst: ASTRONOMISCHES INSTITUTE, TUBINGEN country: WEST GERMANY esa: X ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: Two FOC images through the F150W filter should establish the location of the line_2: HII regions around the nucleus. In estimating exposure times we had to convert line_3: the observed IUE fluxes, which are an integral over typically 10" x 10" to line_4: fluxes per (arc sec)2. This requires an estimate of the distribution of the line_5: gas and stars which we are just trying to establish. line_7: Optical F/96 images of the [OIII] emitting gas and the continuum to clarify line_8: the exact position of the extended emission line gas around the NE spiral arms. line_10: A long slit far ultraviolet spectrum which covers the very bright NW HII region line_11: (r=10.9" PA=332D this is knot 1 of Snijders et al. and knot 5 of Schild et al.) line_12: and a bright HII region in the NW arm (r=15", PA=47D) with peculiar UV emission line_13: lines. line_15: From the IUE images alone the location of this gas is not clear; it might line_16: actually be the same as the high ionization interarm [OIII] gas identified line_17: by Balick and Heckman (1985), and not belong to the HII region. ! question: 4 section: 1 line_1: Ground-based observations are limited to a resolution of 1" to 2", which is line_2: simply not good enough in the crowded inner region of NGC 1068. The available line_3: IUE images have even lower angular resolution than the optical ground-based line_4: data. ! question: 6 section: 1 line_1: If the F 150W filter does not support geocoronal OI emission we will need a line_2: solar zenith angle larger than 100 degrees to remove the remaining OI emission line_3: from the UV exposures. The need to observe NV 1240 rules out the use of F130LP line_4: for the spectrographic images. ! question: 7 section: 1 line_1: We expect to use the RGO Starlink VAX 780 to do most, and perhaps all our data line_2: reduction and image processing. ! question: 10 section: 1 line_1: We expect that RGO and the Astronomical Institute at Tubingen will support us. ! question: 13 section: 1 line_1: The Seyfert 2 Galaxy NGC 1068 will be observed with the FOC using the long slit line_2: and imaging facilities. The object of the project is to study the massive line_3: starburst in the inner spiral arms and the extended emission line gas well away line_4: from the Seyfert nucleus. ! !end of general form text general_form_address: lname: BOKSENBERG fname: ALEC title: PROF. category: PI inst: ROYAL GREENWICH OBSERVATORY addr_1: MADINGLEY ROAD addr_2: CB3 0EZ city: CAMBRIDGE country: UNITED KINGDOM phone: (44) 223 374000 telex: 817235 ! lname: SNIJDERS fname: TOON category: CON inst: ASTRONOMISCHES INSTITUT addr_1: WALDHAUSER STRASSE 64 addr_2: D-7400 city: TUBINGEN 1 country: GERMANY phone: (49) 7071-292486 ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: NGC1068-NUC descr_1: NUCLEUS OF SEYFERT 2 GALAXY pos_1: RA=2H 40M 07.06S +/- 0.03S, pos_2: DEC=-0D 13' 31.46" +/- 0.05" equinox: 1950 pm_or_par: N rv_or_z: Z=0.0037 acqpr_1: EXT plate_req: N plate_avail: N comment_1: THIS TARGET IS USED FOR POSITIONAL comment_2: REFERENCE ONLY AND WILL NOT BE comment_3: OBSERVED. comment_4: TOO BRIGHT FOR GASP fluxnum_1: 1 fluxval_1: V=11.3 +/- 0.2 ! targnum: 2 name_1: NGC1068-P1 descr_1: COVERS WESTERN HALF OF NUCLEAR ZONE pos_1: R=10" +/- 0.5", pos_2: PA=275D +/- 5D, pos_3: FROM 1 equinox: 1950 pm_or_par: N rv_or_z: Z=0.0037 acqpr_1: EXT plate_req: N plate_avail: N fluxnum_1: 1 fluxval_1: V=11.3 +/- 0.2 fluxnum_2: 2 fluxval_2: F-CONT(1500)=4 +/- 3E-16 ! targnum: 3 name_1: NGC1068-P2 descr_1: COVERS EASTERN HALF OF NUCLEAR ZONE pos_1: R=8.5" +/- 0.5", pos_2: PA=46D +/- 5D, pos_3: FROM 1 equinox: 1950 pm_or_par: N rv_or_z: Z=0.0037 acqpr_1: EXT plate_req: N plate_avail: N comment_1: FLUX TYPICAL FOR SPIRAL ARMS comment_2: IGNORING PROBABLE CLUMPING fluxnum_1: 1 fluxval_1: V=11.3 +/- 0.2 fluxnum_2: 2 fluxval_2: F-CONT(1500)=4 +/- 3E-16 ! targnum: 4 name_1: NGC1068-P3 descr_1: COVERS [OIII] EMISSION BETWEEN NE SPIRAL descr_2: ARMS pos_1: R=14" +/- 0.5", pos_2: PA=45D +/- 5D, pos_3: FROM 1 equinox: 1950 pm_or_par: N rv_or_z: Z=0.0037 acqpr_1: EXT plate_req: N plate_avail: N comment_1: THIS [OIII] FLUX IGNORES comment_2: CLUMPING AND IS RATHER UNCERTAIN fluxnum_1: 1 fluxval_1: V=14.5 +/- 0.5 fluxnum_2: 2 fluxval_2: F-LINE(5007)=1.0 +/- 0.5E-14 fluxnum_3: 3 fluxval_3: W-LINE(5007)=2.5 +/- 1.7 ! targnum: 5 name_1: NGC1068-P4 descr_1: COVERS TWO STRONG KNOTS IN NE AND NW ARMS pos_1: R=10.5" +/- 0.4", pos_2: PA=17D +/- 3D, pos_3: FROM 1 equinox: 1950 pm_or_par: N rv_or_z: Z=0.0037 acqpr_1: EXT plate_req: N plate_avail: N comment_1: COVERS THE TWO BRIGHTEST HII comment_2: REGIONS IN THE NE(FLUX REF 3) AND comment_3: NW (FLUX REF 2) ARMS.
