... comparison of the system performance for alfa and lbw at OH (.ps) ( .pdf ) . ... 7.2 Jy at 1666) . ... Since the alfa cals do not work at 1666 Mhz the metrics used were srcDeflection/Tsys (G/T) and the ratio of G/T for alfa and lbw. ... The za's for the measurements were alfa:7.1, lbw:11.5 degrees. ... Using the fluxes of 7.2 Jy, the sefd for the measurements are: Alfa: 4.3,6.0 Lbw: 2.4,2.3 Jy. ... For alfa to match the sensitivity of lbw alfa needs to integrate (6.0/2.35)^2 = 6.5 times longer. ...
