Description:
   This catalog gives differential meridian positions for 670 F-type stars
   in the declination zone 15 deg. to 45 deg. The transits have been
   observed photoelectrically through a Hog grid. FK4 stars have been used
   as reference stars. The internal accuracy of individual measurements is
   shown to be 0.013s in right ascension and 0.30" in declination for
   brighter stars in good observing conditions. It may decrease to 0.020s
   and 0.38" for fainter stars observed in poor conditions. Both weighted
   means and unweighted means are given as are mean epochs. Positions are
   reduced to B1950.0 without proper motions.
