Abstract

In this paper we publish our final data from our extended program of the observation on 13-color medium-narrow-band photometric system. We have observed essentially all of the stars brighter than the fifth visual magnitude north of -20d, and esentially all of the stars brighter than fourth visual magnitude south of declination -20d. The observations have been carefully tied together and we believe that the system is homogeneous to an unusual degree over the entire sky.

The effective wavelengths of the filter-bands have been discussed in detail and a new absolute calibration, based upon all of the available data is derived. The photometric system should be useful, therefore, for the standardizationof other photometric systems, as well as the narrow-band spectro-photometry.
