plate_id int meta.id Plate identification number
archive_id int meta.id Archive identification number
solution_num short meta.number Solution number in the solution set
iteration short meta.record Iteration number
color_term float stat.fit.param Color term of the plate, characterizing color response of the emulsion and filter used
