2/27/2014 David Lawrence This directory is now obsolete and its contents have been removed. The calibration constants are now stored in the CCDB which may be accessed via MySQL or SQLite file. The MySQL DB is the definitive source and a new SQLite DB file is generated from that nightly. Using MySQL will mean you are always up to date with the latest constants, but can be slower for programs to start up as they must read from the network. The SQLite file is generally very fast, but will require you to occasionally download a new file in order to get the latest constants. To use the MySQL DB, set the following: setenv JANA_CALIB_URL mysql://ccdb_user@hallddb.jlab.org/ccdb To use the SQLite DB, see the instructions here (note the link to the latest SQLite file at the bottom of the page) https://halldweb1.jlab.org/wiki/index.php/SQLite-form_of_CCDB_database contact: davidl@jlab.org
