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.
* The notes and remarks were added from the publication as a new file
"notes.dat" by C.-H. Joseph Lyu [Hughes STX/NASA]
* 14-Dec-2009: identifications, accurate positions and remarks
were added by B. Skiff.
