Broad-band photometry of selected southern ultraviolet-bright stars.

| A survey of ultraviolet objects
An all-sky survey of ultraviolet objects is presented together with astatistical analysis that leads to the conclusion that there is asignificantly higher population of hot subdwarfs lying below themain-sequence than hitherto thought. The distribution of all ultravioletobjects, main sequence ultraviolet objects, and MK unclassifiedultraviolet objects are shown in galactic coordinates, and the absolutemagnitudes and color-color diagrams for these groups are presented.Scale heights are derived, giving values similar to planetary nebulaefor the hottest groups.
| 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.
