TABLE  cepheid

Contains Cepheids identified in GDR1

This table contains Cepheid parameters for the identified Cepheids in table
variable_summary (classification="CEP"). In the analyses only observations
with rejectedByVariabilityProcessing=false are included, as found in table
PhotVariableTimeSeriesGfov.
