Photometry of stars in the uvgr system
Photoelectric photometry is presented for over 400 stars using the uvgrsystem of Thuan and Gunn. Stars were selected to cover a wide range ofspectral type, luminosity class, and metallicity. A mean main sequenceis derived along with reddening curves and approximate transformationsto the UBVR system. The calibration of the standard-star sequence issignificantly improved.

VRI photometry of selected SAO stars
Johnson V, R, and I photoelectric photometry has been obtained for 199SAO stars in support of the Near Infrared Photographic Sky Survey. Thesedata are utilized in the calibration of survey photographs and arepresented here to assist other programs reliant upon access tophotometry in the photographic infrared.
