Pac. 104 553 1992 1992PASP..104..553O Photometry, CCD Stars, standard Multiple nights of CCD observations of NGC 7790, NGC 7006, and NGC 4147 are combined in order to establish a deep sequence of photometric standards whose errors have been objectively derived through statistical comparisons. In addition to extending these previously studied fields to a fainter limit, the range in observed color is increased making the mean sequences more suitable for deriving photometric transformation coefficients.
