Abstract This proposal contains observations which will help to complete a number of FOS IDT scientific programs. 1) Nearly simultaneous HST and optical observations of emission line profiles will be used for models of the emission line region. 2) Images of QSOs with low redshift absorption line systems will characterize the type and impact parameter of the absorbing galaxy. ------------------------------------------------------------------------------------ ------------------------------------------------------------------------------------ 9.

Description of proposed observations. PKS0454-220: A 1200s exposure with WFC 2 and F702W. 3C 286: A 1200s exposure with WFC 2 and F702W. PG2302+029: A 1500s exposure with G270H, the RED detector and the 1" round aperture will be done after a binary search target acq. with the large aperture. ------------------------------------------------------------------------------------ 4. Justification of need for HST observations. HST observations are required because the seeing of ground-based observations is not good enough to reveal the absorbing objects hidden in the glare of the background QSOs. Page 3 ------------------------------------------------------------------------------------ 9. Description of previous HST work. Collaborators have received data from a number of GTO programs, SAT, and ERO programs. Related programs which have had observations are as follows: 1026 - ``UV Spectra of Low-Redshift-QSOs'', 1027 - ``UV Spectra of QSOs with z$> 3.1$'', 1029 - ``Spectropolarimetry of QSOs, Blazars, and AGN'', and 1033 - ``Search for Misdirected BL Lac Objects''. Low resolution observations of three high redshift QSOs have not revealed any with light at He II lambda 304. Observations of UM 675 have shown that any He I Gunn--Peterson effect is small, that He I absorption lines are not strong, that predictions of the ``Lyman valley'' may be correct, and that low redshift Ly-alpha is more prevalent than expected. Observations of low redshift QSOs (including 3C 273) have shown even more clearly that Ly-alpha absorption occurs in greater numbers than expected, as well as showing emission--line profile differences more clearly than from earlier data. Unexpectedly, Ly-alpha is narrower than H-alpha. ``HST Imaging of the Inner 3 Arcseconds of NGC 1068 in the Light of [O III] lambda5007'', I.N.Evans, H.C.Ford, A.L.Kinney, R.R.J.Antonucci, L.Armus, and S.Caganoff, {\it Ap.J.(Lett.)}, {\bf 369}, L27, 1991. ``Faint Object Camera Observations of a Globular Cluster Nova Field'', B.Margon, S.F.Anderson, R.A.Downes, R.C.Bohlin, and P.Jakobsen, {\it Ap.J.(Lett.)}, {\bf 369}, L71, 1991. ``Far--Ultraviolet Spectroscopy of the Quasar UM 675 with the Faint Object Spectrograph on the Hubble Space Telescope'', E.A.Beaver, E.M.Burbidge, R.D.Cohen, V.T.Junkkarinen, R.W.Lyons, E.I.Rosenblatt, G.F.Hartig, B.Margon, and A.F.Davidsen, {\it Ap.J.(Lett.)}, {\bf 377}, L1, 1991. ``The Ultraviolet Absorption Spectrum of 3C 273'', J.N.Bahcall, B.T.Jannuzi, D.P.Schneider, G.F.Hartig, R.Bohlin, and V.Junkkarinen, {\it Ap.J.(Lett.)}, {\bf 377}, L5, 1991. ``Faint Object Spectrograph Spectroscopy of Resolved Structure in the Nucleus of NGC 1068'', S.Caganoff, R.R.J.Antonucci, H.C.Ford, G.A.Kriss, G.Hartig, L.Armus, I.N.Evans, E.Rosenblatt, R.C.Bohlin, and A.L.Kinney, {\it Ap.J.(Lett.)}, {\bf 377}, L9, 1991. ``Faint Object Spectrograph Observations of the Low-Luminosity Seyfert Galaxy NGC 1566'', G.A.Kriss, G.F.Hartig, L.Armus, W.P.Blair, S.Caganoff, and L.Dressel, {\it Ap.J.(Lett.)}, {\bf 377}, L13, 1991. ------------------------------------------------------------------------------------ 10. Resources to be supplied by investigator's institution(s). The majority of the resources required for this project other than the normal facilities of a university (librarys, offices, etc.) were supplied by NASA to the members of the FOS IDT for these projects. These include all the computing facilities required for the completion of data reduction and analysis. Optical and IR ground--based observing facilities and support are provided by the University of California and the University of Arizona. ------------------------------------------------------------------------------------ 11.
