资源简介：
URAT is a follow-up project to the successful UCAC project using
the same astrograph but with a much larger focal plane array and a
bandpass shifted further to the red. Longer integration times and
more sensitive, backside CCDs allowed for a substantial increase in
limiting magnitude, resulting in about 4-fold increase in the average
number of stars per square degree as compared to UCAC.
