We have presented and discussed several techniques for analysing calibrated Doppler velocity residuals collected in integrated sunlight, with the principle aim of studying the phenomenology of the solar low-degree, p-mode oscillations. In addition, we have discussed a method for taking advantage of the extra statistical precision afforded, over the 5-minute region, by the simultaneous collection of data at more than one site - even with a substantial fill of such "overlaps'', the analysis demonstrates that any gains are somewhat reduced if the quality of the data from each of the sites comprising the overlap differs.
