Transformation procedures from the FK4 reference system of B1950.0 to the FK5 reference system of J2000.0 have been developed by Standish (1982) and by Aoki et al. (1983). We review here these procedures and discuss the differences between them. Especially we note that among researchers of this field a misunderstanding still exists in the problem at which stage the equinox correction should be applied. We show that the equinox correction should be applied in the precessing frame as Aoki et al. did. We also show that the epoch of the transfer from the FK4 to the FK5 in the transformation procedure is related to the systematic and individual corrections to the FK4.
