A catalog of precise reference star positions for the astrometry network of the international comet P/Halley compaign Abstract image available at:http://adsabs.harvard.edu/cgi-bin/nph-bib_query?1987A&AS...71..525D&db_key=AST
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.
Photoelectric Observations of Stars near Northern Hemisphere Selected Areas Not Available
