... If it is less than 90 degrees we have the prograde motion (i.e. counterclockwise motion, if one looks from the north pole of ecliptic), otherwise the motion is retrograde , clockwise. ...
... In addition, compared to the biaxial case, the influences of the triaxiality on the prograde and retrograde diurnal polar motions excited by ocean tide component K1 are estimated as -1.4 microarcsec and -0.95 microarcsec respectively, which should be ...
