Description:
   The catalog results from a survey for distant Field K giants in
   the Galactic halo made for purposes of locating a chemically and
   kinematically unbiased sample out to about 25 kpc from the Sun.
   The motivation for the study and sample selection are outlined by
   Ratnatunga & Freeman (1985), while details and analysis of the
   results will be found in Ratnatunga & Freeman (1989).
   Three high-galactic-latitude fields each of 20 square degrees,
   designated by their Selected-Area identifications, include the
   following:
     SA 141 (l=240,b=-85); SA 189 (277, -50); and SA 127 (272, +38),
   and have the apparent magnitude range 13 < V < 16 and color range
   (B-V) > 0.9. Stars were selected from PDS photographic photometry
   of Schmidt plates (see Ratnatunga 1983, catalog #2121). K-giant
   selection used the Mgb+MgH feature at 5100A from digital image
   analysis of PDS scans of ESO 1-m Schmidt telescope objective-prism
   spectra with 450 A/mm at H-gamma resolution on IIIa-J plates
   exposed through a Schott GG475 filter. Luminosity confirmation,
   line-of-sight velocities, and metallicity were determined from 2-A
   resolution slit spectra taken with the 4-m Anglo- Australian and
   1.9-m Mount Stromlo telescopes. Cross identifications exist for
   some stars in the SA 141 SGP field only.
