Abstract

We present UBV(RI)_C photometry of 212 stars from Landolt's list of equatorial standards. Our observations are tied to the system defined by Cousins's E-region standards. A comparison of our results with Landolt's reveals reasonably good agreement for (V-R)_c and (V-I)_c, but marked systematic differences for (B-V) and (U-B). The UBV systems of Cousins and Landolt are evidently not the same and both probably differ from Johnson's original system.
