Track-sharing, single-field observations
In this case, the telescope time is equally divided between the
observed sources. This yields
(23)
(24)
Note that it is technically feasible to observe sources in track-sharing
with different integration times. This case is not implemented yet in the
sensitivity estimator and the different sensitivities should be computed
independently. As for single source projects,
is set to 1.6 in
track-sharing mode.
