V/48        Field Type II Cepheids   (Harris 1985)
================================================================================
A Catalogue of Field Type II Cepheids
    Harris H.C.

ADC_Keywords: Stars, variable

Description:
  This catalog contains two data files of Type II Cepheids. The primary
  file consists of 152 Cepheids. These Cepheids are farther than 600 pc
  from the Galactic plane, and all of them are likely field Type II (low
  mass or Population II stars) Cepheids. The second file contains 56
  additional stars that are likely, but more uncertainly, Type II
  Cepheids. These additional stars either have large Z distances but
  lack of reddening estimates or lie close to the Galactic plane
  identified as Type II base upon independent evidence (Petit 1960;
  Woolley 1966; Szabdos 1977; Wallerstein et al. 1979; Lloyd 1983;
  Harris et al 1984). Both of these two files have the same record
  format for each Cepheid. The format includes star name, equatorial
  (1900) and galactic coordinates, period, approximate mean magnitude,
  distance from the Sun and from the Galactic plane, computed reddening,
  and the most recent supplement to the General Catalog of Variable
  Stars (GCVS) where the star is listed.
