Principal Investigator Institution Country Telephone Dr. Holland C. Ford SPACE TELESCOPE SCIENCE INST USA (301) 338-4803 ------------------------------------------------------------------------------------ 7. Abstract WF/PC narrow band images will be used to isolate ionized gas clouds near the nuclei and to look for organized structure such as disks, bubbles and jets. FOS spectrophotometry from 1200A to 7000A will be used to establish density, temperatures, chemical composition, ionization mechanisms, and reddening in the emission regions near the nucleus. Line profiles and radial velocities will be used to investigate broadening mechanisms such as turbulence, gas flows, and rotation. Small aperture spectra of the nucleus will be used to look for a photoionizing continuum and for line broadening in the nucleus, and will be used to establish physical conditions and dynamics of the nuclear gas. UV absorption lines will be searched for in the nuclear continuum in order to measure the amount and distribution of gas along the line-of-sight through the parent galaxy. ------------------------------------------------------------------------------------ 8.

Cycle 2: 201-216 ------------------------------------------------------------------------------------ 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 All WF/PC imaging with a center wavelength blueward of 5000 Angstroms requires UV flood ------------------------------------------------------------------------------------ 12. This is an integrated program to study the structure, distribution, dynamics, and ionization of gas in LINERS. The program will be complete when all spectroscopy and imaging have been completed on six of the eight galaxies. Data should not be released until 1 year after completion of the sixth galaxy. ------------------------------------------------------------------------------------ 13. WF/PC images will be used to study the structure and distribution of ionized gas in low redshift LINERS. FOS spectra will be used to establish physical conditions, chemical composition, ionization mechanisms, and dynamics of gas near the nucleus. Small-aperture spectra of the nucleus will be used to establish the presence or absence of a photoionizing continuum and to measure physical conditions and dynamics of the nuclear gas. ------------------------------------------------------------------------------------ 11.
