Abstract PART 2 consists of replacement targets for objects pulled from the original submission because targets had been previously observed in other programs. The Absorption Line Survey of bright quasars provides a homogeneous data base for studying fundamental questions about the origin and evolution of gaseous systems in the universe. The initial results determine at small redshifts the number densities of Ly-ALPHA systems, of metal-lines and extragalactic halos, of Lyman-limit systems, of associated absorption systems, and the shapes and intensities of quasar emission lines and spectral energy distributions. The survey reveals that much of the sky is covered by high or very high velocity metal-line clouds present in the Galactic halo. A larger sample, which includes the requested Cycle 3 observations, is required to answer many important questions.

This proposal is part of the Cycle 3 QSO Absorption Line Key Project 4581 of Bahcall et al., and consists of some targets which are replacements for some of the targets in that program found to have duplication problems in the original submission. These observations are to be done as described via the requirements in the Exp Log sheets, following well-established patterns from the rest of the QSO Absorption Line Key Project programs. ------------------------------------------------------------------------------------ 11.
