In observational astronomy, we essentially measure the location,
flux density (at certain frequency and certain time), distance and
angular size of the sources. A parameter space of observational
astronomy can be constructed with the parameters such as the sample size
of sources, frequency (bandwidth and frequency resolution), time
(observing length and time resolution), sensitivity, and angular
resolution of the telescope. Based on the previous experience, we would
always obtain new knowledge of the universe with instruments that fill
in the blanks in the parameter space, e.g. telescopes used for better
surveys (which enlarge the sample sizes of sources), telescopes with
higher sensitivity, angular resolution, frequency resolution or time
resolution.
