Abstract The purpose of this program is to establish the optical and UV spectral energy distribution for one of the nearest and brightest Seyfert 2 galaxies, using the small (0.3") FOS aperture to isolate the broad line and continuum emission regions. Early PC exposures with filters F502N and F547M will be used to isolate the exact location of the maximum continuum brightness from the emission of the narrow line region. The UV continuum spectra will be used to look for absorption due to the halo of the Seyfert or intervening clouds. Emission line intensities and profiles for the broad components will be measured uncontaminated by emission from the galactic disk or narrow line region. The PC exposures will also be used to identify the brightest emission line cloud in the narrow line region. FOS spectra of the cloud will be obtained through the 0.3" aperture. In conjunction with the more detailed information obtained on brighter Seyferts (FOS 14), this study will provide another point of comparison for more generally understanding the Seyfert phenomenon. ------------------------------------------------------------------------------------ 8.

Ford SPACE TELESCOPE SCIENCE USA INSTITUTE ------------------------------------------------------------------------------------ 3. Description of proposed observations. Exposures with the PC will be used to determine the location of maximum brightness of the nonthermal continuum (which may differ from the peak starlight and narrow line emission.) All observations will be made with the 0.3" circular slit. Exposure times for T0109-38 are scaled by the ratio of H-alpha flux to that of NGC1068 over the central 2 x 4 arc seconds. Exposures are calculated to give a S/N of 10 per diode for each spectral range from the UV to 6500 A. Cycle 3 1.20 hours primary, 0 hours parallel Cycle 4 8.60 hours primary, 0 hours parallel ------------------------------------------------------------------------------------ 5. Description of special scheduling requirements. The SV prerequisite programs for all FOS observations in this program are: Prop ID 2195 FOS Target Acquisition Tests All observations Prop ID 1317 Int./Ext. Wavelength Offsets 1st target Prop ID 1318 Spectral Flat Fields 1st target Prop ID 1320 Absolute Spectrophotometry 1st visit of bright targets For those programs performing polarimetry, all include the following: Prop ID 1430 Polarimetric Calibration All observations ------------------------------------------------------------------------------------ 12. ------------------------------------------------------------------------------------ 13. This program will establish the optical and UV spectral energy distributions of one of the brightest and nearest Seyfert 2 galaxies using the small FOS aperture (0.3") to isolate the broad line and continuum emission regions. The UV continuum will be used as a probe of the Seyfert halo and intervening clouds, and line intensities and profiles will be used as diagnostics of the dynamics and physical conditions of the broad line region. Spectra of the brightest knot in the narrow line region will be used to determine physical conditions in narrow line region clouds. ------------------------------------------------------------------------------------ 11.
