New determination of period and quality factor of Chandler wobble, considering geophysical excitations

We obtained solutions for three different time intervals: 1974.0-1994.0, 1994.0-2014.0, and 1974.0-2014.0. The estimated values of Q-factor are much smaller if GMJ excitations are used in addition to atmospheric and oceanic ones, and they are determined with higher accuracy. Our preferred values, valid for the whole interval 1974.0-2014.0, are P=432.86±0.04 days and Q=35.0±0.3.
