CelestiaContent/data/revised.stc

# Revisions to stars listed in Celestia distribution stars.dat
#
# These consist of improvements or revisions to the Hipparcos
# data from which stars.dat was prepared, the addition of some
# bright stars with incomplete data in Hipparcos, and the correction
# of some parallax errors introduced by Celestia's processing of 
# apparently fictitious multiple systems generated by Hipparcos.
# Commonly used sources are listed below, and other sources are 
# referenced in the annotations.
