Top: a projection of the global sky model of de Oliveira-Costa et al. (2008) as viewed from latitude ﹩-30^\circ ﹩ at a local sidereal time of 05:44, overlaid with the PAPER beam response contours before (black) and after (red) the application of a fringe-rate filter optimized for sensitivity. Bottom: a simulation of the corresponding rms visibilities for a 30 m east–west baseline before (black) and after (red) the same fringe-rate filtering. The reduced presence of foregrounds in the simulated visibilities after fringe-rate filtering can be understood as coming from the spatial filter enacted by fringe-rate filtering.
