摘要：

The Birmingham Solar-Oscillations Network (BiSON) consists of 6 solar observatories dedicated to the collection of full-disc solar Doppler velocity data - these data are sensitive to the lowest spatial degrees of oscillation (0 less than or equal to l less than or equal to 4). In Paper I of this series, we described the calibration of raw data from the BiSON instruments to produce solar velocity residuals representing the oscillations of the Sun's surface. In this paper, we discuss the combination of velocity residuals into time series - including a thorough discussion of the treatment of data overlaps between sites - and the analysis of the power spectra computed from such time series to derive the characteristics of the acoustic modes.
