1.5.5 Fringe-frequency - delay source search observations

The approximate positions and strengths of sources within the primary beam of an antenna can be quickly determined by recording data for two five-minute periods at two widely spaced hour angles using only one long and one short baseline. The data can be analysed off-line to produce fringe-frequency versus delay plots, which separate out the individual sources within the antenna beam. See §3.10.4 for further information.
