The systematic differences between the HIPPARCOS catalogue and the
FK5 (Part I)
were derived for the construction of the
FK6 (Part I) .
The results are published in Astronomy and Astrophysics, Vol. 367,
p. 1078 (2001). We provide here software for the computation
of the systematic differences HIPPARCOS - FK5 in position and
proper motion as a function of the right ascension and declination
(no magnitude equation was found). These systematic differences are the
corrections which have to be added to position and/or proper motions
given in the system of the FK5 (Part I) in order to transform them to
the HIPPARCOS system. The systematic relations between the HIPPARCOS
system and other important catalogues are provided here. For detailed information
