Baseline Sensitivity

Table below shows (2) nominal frequency range of KVN receivers at K- and Q-band, (4) typical KVN system-equivalent-flux-density at zenith, (5) antenna gain at the optimal elevation, (6) typical KVN baseline sensitivity for the aggregated recorded data rate of 1024Mbps, the integration time of 100sec (K-band), 60sec (Q-band), and 30sec (W/D-band), and the bandwidth of 256MHz, and (7) typical KVN 3-baseline image sensitivity for the on-source integration time of 8hr.
