The data type srv collects cluster-star identifications in large surveys, like GSC, TYCHO-2, 2MASS and ASCC-2.5.
Cross-identifications have been supplied by Brian Skiff, made from the files built by Wilton Dias which
contain the TYCHO-2 identifications for nearly 200 open clusters or have
been taken from the ASCC-2.5 catalogue.
