Single-source, single-field observations
That's the simplest case. The point source sensitivity in this case is
(21)
where
is the time spent on-source. It is related to the total
elapsed telescope time
through:

For single source projects,
is estimated to be about 1.6. Note
that the exact value will depend on several parameters such as the number
of calibrators and the distance between the source and the calibrator(s).
