2. The Hipparcos measurements

These measurements taken from the Hipparcos Catalogue (ESA, 1997), are given in Table 1. Columns 1 - 5 give the Hipparcos catalogue number, the name, the coordinates (positional identifier) and the Hipparcos magnitude. Columns 6 and 7 give the parallax and its standard error in milli-arcseconds. Columns 8 and 9 give the proper motions in RA and Dec together with the standard error in milli-arcseconds per year. The errors on all data are typical for faint stars. The ground based magnitudes are given in the last column. A discussion of the relationship between these magnitudes and the Hipparcos magnitude is given in Acker et al. (1998).
