G. Thomas et al., AN AUTOMATIC ELECTRONIC COMBINED BLINK-COMPARATOR AND MEASURING ENGINE, Proceedings - Astronomical Society of Australia, 11(1), 1994, pp. 55-57
We have designed and manufactured a multi-purpose electronic, computer
-operated blink-comparator and measuring engine. It has been specifica
lly designed to facilitate the examination of stellar images on Uppsal
a Schmidt photographic plates, identify and establish coordinates of n
ew suspect variable stars appearing on the plates being examined, and
also to derive photometric values for those stars manifesting variabil
ity.
