Overview

rms noise in a single channel for a single visibility is:


[math]\displaystyle{ \frac{2k}{A_{eff}} }[/math] [math]\displaystyle{ \sqrt{\frac{Tsys_i Tsys_j}{\Delta\nu_{ch} t_{ij}}} }[/math]


Where k is Boltzmann's constant, A_eff is the effective antenna area, delta_nu is the channel width, and t_{ij} is the integration time per visibility.
