This field would line_5: cover the nucleus and the two brightest hot spots. The exposures on the object line_6: would be: line_8: I 1. filter F502M 59 min [OIII] + H-Beta + cont. line_9: I 2. F470M 30 min cont (b) line_10: I 3. F501N 59 min [OIII] + cont. line_12: Exposure 1 should enable us to choose the precise optimum settings for the line_13: spectrographic slit. The narrow H-Beta filter F486N would make the transmission line_14: of the redshifted H-Beta emission very velocity dependent. From a combination line_15: of the three exposures above it should be possible to extract the H-Beta line_16: picture with the exception for a slight effect of differential reddening line_17: between 470 and 505 nm. line_19: Spectrographic Mode line_20: ------------------- line_21: To get information on non-circularity of motions two slit positions through the line_22: nucleus in two different position angles is a minimum. For one of these line_23: position angles the slit should be over the bright hot spot near the ! question: 3 section: 2 line_1: center of which is only 1.6" from one of the compact radio sources unresolved line_2: at 2 cm with the VLA. If the direct imaging would show a trace of this source, line_3: the exact position angle would be chosen to cover it. The second slit position line_4: should be chosen along the apparent minor axis as derived from the rotation of line_5: the nuclear narrow-line disk. The exposures would be in the f/48 spectroscopy line_6: mode, format 512x512 pixels: line_8: S 1. first order p.a. 63.4D (243.4D) 75 min line_9: S 2. --- " --- 138D (318D) 75 min ! question: 4 section: 1 line_1: To study the structures on a scale smaller than 0.1" that are present according line_2: to radio results, rotation of hot spots and the structure and kinematics of the line_3: Seyfert nucleus at highest possible resolution ST observations are necessary. ! question: 5 section: 1 line_1: Exposure 1 has to be obtained first for preparation of the spectrographic line_2: observations. line_4: Position angles for the spectrograph slit are given on the log sheet, but might line_5: be modified slightly after examination of the direct image 1. line_7: Comparison arc has to be used for radial velocity measurements. ! question: 7 section: 1 line_1: We expect to perform the standard reductions and image processing with the line_2: software that will be developed at the ST/ECF at ESO or developed for the line_3: STARLINK system. line_5: A software for further processing and analysis of two-dimensional images and line_6: spectral data has been developed for the Stockholm Observatory line_7: computer by one of the proposers (S. Jorsater: Stockholm Obs. Rep. No. 22, line_8: 1984). line_10: The Stockholm Observatory has an Alliant FX/2 line_11: and an image processing system. It is expected that the analysis will be line_12: carried out on this system, probably with the MIDAS package and additional in line_13: house software. ! question: 10 section: 1 line_1: The extragalactic research at the Stockholm Observatory receives annual support line_2: by the Swedish Natural Science Research Council. If accepted this project will line_3: also be supported by the Swedish Space Board. Complimented by the ESO/ECF line_4: facilities our data analysis capability will be quite adequate. ! question: 13 section: 1 line_1: The aim of the program is to study the light distribution, kinematics and mass line_2: distribution in and around the Seyfert nucleus and nuclear hot spots in the line_3: barred galaxy NGC 1365. In particular differences in light distribution and line_4: kinematics as shown in H-Beta and [OIII] lines will be invesigated. ! !end of general form text general_form_address: lname: BOKSENBERG fname: ALEC title: PROF. category: PI inst: ROYAL GREENWICH OBSERVATORY addr_1: HERSTMONCEUX CASTLE addr_2: BN27 1RP city: HAILSHAM, EAST SUSSEX country: UNITED KINGDOM phone: (44) 323-833171 telex: 87451 RGOBSY G ! lname: LINDBLAD fname: PER OLOF category: CON inst: STOCKHOLM OBSERVATORY addr_1: S-133 36 city: SALTSJOBADEN country: SWEDEN phone: (46) 8-717 03 80 telex: 12972 SOBSERV S ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: NGC1365 descr_1: SBB GALAXY WITH ACTIVE NUCLEUS pos_1: RA = 3H 31M 41.802S +/- 0.02S, pos_2: DEC = -36D 18' 26.6" +/- 0.6" equinox: 1950 pm_or_par: N rv_or_z: V=1626 acqpr_1: EXT plate_req: N plate_avail: N comment_1: EXACT POSITION TBD AFTER EXPOSURE comment_2: 1 HAS BEEN EXAMINED ! targnum: 2 name_1: NGC1365-SW descr_1: OFFSET TO THE SW OF THE NUCLEUS OF NGC1365 pos_1: RA = 3H 31M 41.58S +/- 0.02S, pos_2: DEC = -36D 18' 29.2" +/- 0.2" equinox: ^ pm_or_par: ^ rv_or_z: ^ acqpr_1: ^ plate_req: N plate_avail: N comment_1: EXACT POSITION TBD AFTER EXPOSURE comment_2: 1 HAS BEEN EXAMINED. ! targnum: 3 name_1: NGC1365-SKY descr_1: SKY FOR NGC1365 pos_1: RA = 3H 31M 7S +/- 0.1S, pos_2: DEC = -36D 11' 0" +/- 1" equinox: ^ pm_or_par: ^ acqpr_1: ^ plate_req: N plate_avail: N ! ! end of fixed targets !
