TABLE  erosSMCSource

This table contains brief descriptions of the parameters provided for each source in the catalogue of the SMC fields from EROS. The table contains comprehensive summary statistics that are provided for each star in the SMC from EROS-2. Required constraints: Primary key is (seqNum)
