ADC_Keywords: X-ray sources ; Surveys
Mission_Name: UHURU
Description:
The catalog of 161 X-ray sources was observed with Uhuru satellite.
The night-time portions of 125 days of observations were included in
the 3U catalog.
The electronic version of the catalog contains only selected data of
the 3U catalog published by Giacconi et al. (1974ApJS...27...37G 1974ApJS...27...37G):
source locations in equatorial coordinates (1950 equinox) in decimal
degree notation, and count rates measured with Uhuru from 2 to 6 keV
corrected for elevation in the collimator fields of view. The comments
given for the sources consist of general remarks which indicate
peculiar X-ray properties, e.g., spectrum or time scales of
variability, and a "counterparts" comment. Counterparts followed by a
question mark "?" indicate either tentative identification or that the
object is in or near the error region of the X-ray source. Also,
comments with a question mark indicate possible correspondence.
