Notes. The x and y columns correspond to the original coordinates of the data (pre-alignment with SDO/HMI), the ‘Region’ column details which red box from Fig. 3 the pixel is within, the ‘Period’ column denotes the approximate temporal ranges with significance above the 99% confidence interval (max period is 1272 s), and the ‘Amplitude’ column is an estimate of the maximum peak-to-peak value. Errors for the periods and peak amplitudes are difficult to quantify (due to, for example, the varying amplitudes of the apparent oscillations over time, the snap-shot nature of these observations, and noise in the data); however, we are confident that these reported values are within ±50 s and ±20 G of their true values, respectively.
