A Second Catalog of Orbiting Astronomical Observatory 2 Filter Photometry: Ultraviolet Photometry of 614 Stars

Abstract

Ultraviolet photometry from the Wisconsin Experiment Package on the Orbiting Astronomical Observatory 2 (OAO 2) is presented for 614 stars. Previously unpublished magnitudes from 12 filter bandpasses with wavelengths ranging from 1330 to 4250 Å have been placed on the white dwarf model atmosphere absolute flux scale. The fluxes were converted to magnitudes using V=0 for F(V)=3.46x10^-9 ergs cm^-2 s^-1 Å^-1, or m_lambda=-2.5logF_lambda-21.15. This second catalog effectively doubles the amount of OAO 2 photometry available in the literature and includes many objects too bright to be observed with modern space observatories.
