The Birmingham Solar Oscillations Network (BiSON) provides high-quality high-cadence observations from as far back in time as 1978. However, 1985 is the earliest period for which at least three sites were observing regularly.
These data are calibrated from the raw observations into radial velocity and the quality of the calibration has a large impact on the signal-to-noise ratio of the final time series. For details on this procedure please see 10.1093/mnras/stu803.
If you would like a specific time period of data or have a special processing request, please contact us for a bespoke solution. When making use of these data, please cite both 10.1007/s11207-015-0810-0 and 10.1093/mnras/stu803 in any publications. Suggested BibTeX entries are below.
