Description:
   Photoelectric observations of the beta index and of the indices similar
   to those of the Stromgren system have been made for 437 field stars and
   for a number of stars in the Coma Berenices, Praesepe, NGC 6633, and NGC
   1662 clusters. Of the field stars, 377 are A0-A2 stars north of
   declination -5 deg. with V not more than 6.0; in the clusters, A stars
   were observed primarily. The measured values were transformed to the
   standard Stromgren system. The accuracies of one observation are 0.017,
   0.013, 0.016, and 0.014 for beta, b-y, c1, and m1 respectively. The data
   table also gives mean errors.
