The SEI teams at Stanford and LASTI are currently testing the new Cartesian basis bias correction in the isi/common/isi2stagemaster.mdl. Please do not svn update the trunk/isi/common directory from the cds_user_apps repository without talking to someone locally from one of the SEI teams.
For more details, see the log entry made by Hugo Paris on Friday 19 July 2013 titled "BSC/HAM ISI Models & MEDM - CART BIAS Update" in the SEI log.
