Data Model: eFEDS_C001_Hard_PointSources_CTP_redshift_V17

General Description
Multiwavelength properties of the primary counterpart to the eFEDS sources in the Hard X-ray catalog (number two of this table) for which an alternative or additional counterpart can't be excluded. For each counterparts the classification, photometry and redshift is provided. Three sources have an alternative or additional counterpart: the properties can be retrieved by matching the ID_MAIN column with the ID_SRC column in the catalog above.
