Informations.
         relative to: absolute
     reference frame: BCRS
     centre of frame: Gaia
    epoch of equinox: J2000
          time scale: TCB
           reduction: positions are corrected for full relativistic aberration but not for
                      relativistic light deflection in the gravitational field of the Solar System
         coordinates: right ascension, declination
    diff. refraction: no information
            receptor: CCD
           telescope: Gaia's astrometric instruments
           observers: Gaia
 data included in standard data file: no

Comments.
  1. Since in Gaia FPR all observations of Solar system objects were reprocessed, there can be intersections
     with observations of Siarnaq from Gaia DR3 release given in so1038 data unit.

  2. Details concerning specific features of Gaia observations of the Solar system objects are given in
     Tanga et al. (2022) and Gaia Collaboration (2023).
     General information about Gaia FPR is given at www.cosmos.esa.int/web/gaia/fpr.
