Description:
The catalog is derived from wide-field far-ultraviolet (FUV;
1300-1800Å) images of the Large and Small Magellanic Clouds (LMC,
SMC) obtained by the Ultraviolet Imaging Telescope (UIT) during the
Astro-1 (1990 December 1-10) and Astro-2 (1995 March 2-18) missions.
The FUV magnitudes are derived from point-spread function photometry
for 37,333 stars in the LMC (the UIT FUV magnitudes for 11,306 stars
in the SMC were presented by Cornett et al. (1997AJ....113.1011C 1997AJ....113.1011C),
with a completeness limit of mUV ∼ 15mag and a detection limit of
mUV ∼ 17.5. The average uncertainty in the photometry is ∼ 0.1mag.
