Notes. The first three columns correspond to the five independent parts of the quadrupolar modulation, which we have chosen to present using a complex notation for g2M. The quoted error bars are at the 68% confidence level. The quadrupolar modulation amplitude is given in the fourth column, while the mean and standard deviation of g2, estimated from simulations, are provided in the fifth column.
