The 20030714 Training Sample

This sample was released on 14 July 2003. It represents a reprocessing of the earlier WGACAT-derived samples to incorporate a variety of software fixes (including new magnitude scaling factors), as well as additional correlative data: infrared from 2MASS, and radio from NVSS. Additional optical data was also provided from GSC 2.2, but that data has not yet been used in any new classifiers.
