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.

Rocket ultraviolet imagery of the Andromeda galaxy
Far-UV electrographic imagery of M31 is presented which was obtainedduring a sounding-rocket flight with an electrographic Schmidt camerasensitive in the wavelength range from 1230 to 2000 A. The resolution inthe imagery is such that 50% of the energy from a point source isconfined within a circle 40 arcsec in radius. Two conspicuous featuresare observed in the UV image of M31: one corresponding to a brightassociation (NGC 206) in the SW region of the disk and one centered onthe galactic nucleus. Indications of the general spiral-arm structureare also evident. Absolute photometry and brightness distributions areobtained for the observed features, and both the central region and NGC206 are shown to be diffuse sources. It is found that the brightnessdistribution of the central region is a flat ellipse with its major axisclosely aligned with the major axis of the galaxy, which favors a sourcemodel consisting of young early-type stars close to the galactic planeand constitutes strong evidence against a nonthermal point source at thegalactic center.
