Proper motion in declination, , in arcsec per year.
[]The proper motions are generally taken from the CCDM. The
sources are generally the same as for positions (see explanations given
under fields 4 and 5, and under fields 7 to 10). As for positions,
there may be differences between the proper motions given in Annex 1
and in the main catalogue. The equinox of the proper motion is that of
the source catalogue (this information is not given in Annex 1).
