This line_4: implies that these objects would appear as Seyfert 1's line_5: if viewed from another direction, so the distinction line_6: between the two classes could be a largely an line_7: orientation effect. (The polarization position angles line_8: of Seyfert 2's are always perpendicular to the radio line_9: source axes. This scattering geometry indicates that line_10: the Seyfert 2's would appear as Seyfert 1's line_11: if viewed along the radio jet axis.) line_12: We need to find out whether or not the polarized flux line_13: spectra of Seyfert 2's are really INDISTINGUISHABLE line_14: from the flux spectra of Seyfert 1's by looking for the line_15: high excitation lines, the Fe II, and the continuum shape line_16: in the UV. We also need to measure the wavelength-dependence line_17: of continuum polarization in the line_18: UV to determine the nature of the scatterers. ! ! end of abstract general_form_proposers: lname: MILLER fname: JOSEPH mi: S inst: LICK OBSERVATORY country: USA ! lname: ANTONUCCI fname: ROBERT title: P.I. inst: UC, SANTA BARBARA country: USA ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: We plan four spectropolarimetry scans of NGC1068. First we line_2: use FOS/BL, G270H, and the 0.3" aperture for a brief integ; line_3: then a brief integ. with 1.0". Next we do a long integ. line_4: with the 4.3" aperture for good SNR. Finally we do a long line_5: integ. with the 4.3" aperture and the G190H grating. line_6: All exposures use the B waveplate and 4 position angles. line_7: The nucleus is burned out on the GSSS plate, and spatially line_8: resolved on the GTO images. The position specified is line_9: from I Evans, based on the GTO/SAO optical continuum image. line_10: Based on the acquisition experience of the FOS GTO team, line_11: George Hartig tells us we can acquire succesfully with a line_12: Binary Search followed by a fine Peak-Up. He advises us to line_13: use a FAINT limit of 33000 and a BRIGHT limit of 720000, line_14: and 66 sec total integ for the B.S. For Peak-Up he advises line_15: 10 sec per pointing, and first a 3x3 with the 0.3" aperture, line_16: covering 0.4" at 0.2" spacing; this is to be followed by a line_17: 4x4 stage with the same aperture, using 0.06" spacing. That line_18: is what we have attempted to key in below. ! !end of general form text general_form_address: lname: ANTONUCCI fname: ROBERT category: PI inst: UC, SANTA BARBARA addr_1: PHYSICS DEPARTMENT city: SANTA BARBARA state: CA zip: 93106 country: USA phone: 805-893-4350 ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: NGC1068 descr_1: GALAXY; SEYFERT GALAXY pos_1: RA = 2H 42M 40.69S +/- 1", pos_2: DEC = -00D 00' 48.5" +/- 1" equinox: 2000 rv_or_z: Z=0.003 comment_1: NUCLEAR NONSTELLAR LIGHT (TOTAL comment_2: LIGHT WITHIN 1"V ~ 12.5). fluxnum_1: 1 fluxval_1: V = 14.32 fluxnum_2: 2 fluxval_2: F-CONT(1300) = 2 +/- 1 E-14 fluxnum_3: 3 fluxval_3: F-CONT(1900) = 2 +/- 1 E-14 fluxnum_4: 4 fluxval_4: F-CONT(2700) = 2 +/- 1 E-14 ! ! end of fixed targets !
