TABLE  twomass

The K-selected sample, K < 12.75 represents the primary 6dFGS input catalogue. The H and J selected samples reach H < 13.00 and J < 13.75. The programme ID numbers (progid in the target table) for the K, H and J selected surveys are 1, 3 and 4 respectively. Required constraints: Primary key is (targetid)
