maj.a.: half-power beam width (HPBW) for the major axis of the best-fit three-dimensional Gaussian component to the synthesised beam. min.a.: HPBW for the minor axis. P.A.: position angle of the major axis (E of N). rms: the root-mean-square noise fluctuations in signal-free channels in units of Jansky per beam area. S/N: signal-to-noise ratio or ``dynamic range'' in the channel with strongest signal. |
