The Cousins VRI System: A Consistency Test of Equatorial and Southern Standard Stars
Abstract image available at:http://adsabs.harvard.edu/abs/1996AJ....111.1338T

Secondary UVBY standards in the Harvard E-regions
Photoelectric uvby photometry for 201 stars which are already UBV (RI)cstandards is presented. The photoelectric data are closely tied to theCousins uvby standards and the stars should be suitable for use asfainter (7-11 mag) secondary standards.

UBV (RI)c standard stars in the E- and F-regions and in the Magellanic Clouds - a revised catalogue.
