We understand why you might be interested in obtaining these catalog files, but are concerned that they might be misused. We have merged catalogs from several different sources, and used fairly subjective criteria to rank our preferences. We have used simple, automated schemes to compute magnitudes and remove aftershocks. To the extent that the original catalogs are not valid research tools, neither are ours! Please read the accompanying documentation, and ask whether these catalogs suit your purpose.
