... The principal results are T_eff=23300 K, log g=3.35, {n_H}/{n_He} With T_eff, log g, and pulsation properties very similar to the C-poor and N-rich helium star V652Her, evolutionary mechanisms which can result in very different surface compositions for the two stars must be examined. Based on observations obtained at the European Southern Observatory, La Silla, Chile, and with the IUE satellite retrieved from the IUE archive at the World Data Centre, Rutherford Appleton Laboratory, UK . ...

Next: ZGSC (Compressed GSC) and XSKYMAP . ... This is a preliminary report on an investigation of the quality and properties of plates digitized during creation of the Guide Star Catalog (GSC). The results will be vital for reclassifying GSC objects. ... Many objects are measured on more than one plate, and thus have multiple catalog entries. ... Among the shortcomings of the GSC are: biased magnitudes and incorrect classifications for certain objects, presence of artifact objects. ...
