At a given Declination, there is an allowed hour angle range set by the allowable elevation range and the desired PSF elongation limits. At Declinations where the source passes near zenith at the VLA, there are also restrictions on low HA limits. We describe these below.  Figure~\ref{fig:AoverBvsHAcontour} shows the contours of PSF axis ratio A/B  in the Declination-HA plane. plane for the array in the B configuration. Figure~\ref{fig:AoverBvsHA_BnA} shows the A/B for the VLA in the BnA hybrid.
