Notes. Columns 1 and 2 give (Galactic) source names and an alias where appropriate. Column 3 gives the maser transitions: 12 GHz and 22 GHz are CH3OH and H2O masers, respectively. Columns 4 and 5 give the trigonometric parallaxes and distances. Columns 6–8 give the proper motion components in the eastward (μx = μαcos δ) and northward directions (μy = μδ) and the LSR velocity of the central exciting star. References are given in Col. 9.
