Definitive Sun-as-a-star p-mode frequencies: 23 years of BiSON observations
Abstract
We present a list of `best possible' estimates of low-degree p-mode frequencies from 8640 days of observations made by the Birmingham Solar-Oscillations Network (BiSON). This is the longest stretch of helioseismic data ever used for this purpose, giving exquisite precision in the estimated frequencies. Every effort has been made in the analysis to ensure that the frequency estimates are also accurate. In addition to presenting the raw best-fitting frequencies from our `peak-bagging' analysis, we also provide tables of corrected frequencies pertinent to the quiet-Sun and an intermediate level of solar activity.
