Notes. All positions refer to Epoch J2000. Columns 6, 7 indicate the proper motions derived from our data (μa = μαcos(δ) and μb = μδ). Columns 8, 9 indicate the values adopted in the analysis, in general a weighted average of our measurements and those of Ducourant et al. (2005), except for (a) data from Itoh et al. (2008), (b) from the Hipparcos catalog Perryman et al. (1997), (c) from Zacharias et al. (2004). For HH 30, the adopted value was discussed in Guilloteau et al. (2008).
