Description:
   BVR photoelectric photometry and positions are reported for 437 stars in 49
   Palomar Sky Survey fields. A relation is derived between the Johnson BVR
   photometry and the E and O photographic magnitudes on the Palomar plates.
   The BVR photometry, the E and O magnitudes, and the 1950 positions are
   presented in the accompanying catalog.
