Comments.
   1. The coordinates of Uranus are given also to produce the relative 
      coordinates of the satellites if necessary.
   2. Theoretical positions for the satellites were calculated
      using GUST86, and for Uranus using DE403 ephemerides.
   3. Some of the observations published by Veiga et al. were excluded since they were republished in 2015 by Camargo et al.
      (Astrometry of the main satellites of Uranus: 18 years of observations. Astronomy & Astrophysics. V. 582. P. A8.)

Format.
  1. Index of satellite (0 for Uranus).
  2. Universal time of the observation as a Julian day 
            and the fraction minus 2440000 for the mean instant of the observation.
  3. Observed ICRS geocentric hour of right ascension
  4. Observed ICRS geocentric minute of right ascension
  5. Observed ICRS geocentric second of right ascension
  6. Observed ICRS geocentric degree of declination
  7. Observed ICRS geocentric arcminute of declination
  8. Observed ICRS geocentric arcsecond of declination
  9. Observed - theoretical right ascension position, arcsec
 10. Observed - theoretical declination, arcsec
