Despite saturation effects present in the red portion of the HES objective-prism spectra, the data were recoverable and quantitative selection criteria could be applied to select the sample. Analyses of medium-resolution (∼2Å) follow-up spectroscopy of the entire sample, obtained with several 24m class telescopes, yielded 145 new metal-poor stars with metallicity [Fe/H]←2.0, of which 79 have [Fe/H]←2.5 and 17 have [Fe/H]←3.0. We also obtained C/Fe estimates for all of these stars. File Summary:

Note (1): For 5 sources, HE 0240-0009, HE 0318-2642, HE 0409-1212, HE 0527-3931 and HE 0437-1331, there are two set of measurements, identified by f and b after the source name. Note (2): Parameters in table11.dat only. Note (3): * = star has been rediscovered as metal-poor star with [Fe/H]←2.0 Note (4): Comment as follows: HB = horizontal branch He = He lines in the spectrum em = emission lines in the spectrum pec = peculiar dist = distorted Ca K line comp = possibly composited spectrum of two objects
