title = "Distribution of MDIP-mode power correlation coefficients",
abstract = "We have analysed a 72-day MDI spherical-harmonic time series to examine temporal variations of p-mode power and their correlation. The power variation is computed by a running-window method after the previous study by Roth (2001), and then distribution function of power correlation between mode pairs is produced. We have confirmed Roth's result that there is an excess of anticorrelated p-modes pairs with close frequencies. On the other hand, the amount of excess was somewhat smaller than the previous study. Moreover, the distribution function does not exhibit significant change when we paired modes with non-close frequencies, implying that the excess is not due to mode coupling. We discuss the possibility of statistical bias playing the central role in producing the excess.",
