Comments.
  Note that the data given in Brown et al. (2021) have misprints: for the first three
  observations of Queta coordinate Y is given with the wrong sign. We fixed this error.

Format.
 1. Julian date of observation (JD)
 2. Relative right ascension (X, mas)
 3. Relative declination (Y, mas)
 4. Positional uncertainty for both X and Y (sigma, mas)
