    Entry number 324286

    keyword=GEM database updated

    The GEM database (/adaqfs/halla/adaq/happexsp/prex/DB/20100519/db_L.gem.dat) has been updated to reflect the recent measurement of the positions of the x2/y2 and u2/v2 chambers. This is a change to the variables L.gem.(x/y/u/v)2.position. The old values are still recoreded in the db_L.gem.dat.backup file. The positions previously recorded in the database were wrong by about a factor of 2.
