The reference systems for the determination of UT1 and polar coordinates are discussed. Some arguments are given in support of the adoption of the mean pole origin (MPO) defined by the mean latitudes of the observatories. Taking into account the frequency response of the filters used by the BIH and the U.S.S.R. Time Service, the effects of the errors of the adopted nutational coefficients and tidal variations of the vertical are estimated.
