Description:
    An objective prism survey for stars of spectral type F2 and earlier in
    a North Galactic Pole region was made with the Hamburg 80-120cm
    Schmidt telescope (dispersion 590Å/mm at Hγ).

    The accurate positions of these stars were recovered from the
    finding charts for stars without BD identification (table II)
    by B. Skiff (Lowell Obs.) in 2009.

History:
  * The original version was keypunched at CDS before 1974.
  * 14-Dec-2009: identifications, positions and remarks were added by
                 B. Skiff in December 2009.
