Some care has been taken to make all of the tasks called by processImage sensitive to which measurement framework and schema version are in use, so that the pipeline will work with either measurement task. However, the developer should be careful when accessing or adding fields to the schemas to know which measurement task and which naming conventions are in effect. For new code, we encourage the use of the meas_base measurement framework and schema version=1 tables.
NOTE: If you are reading this document prior to the changeover to the end of Summer 14, just the opposite instructions will hold for using the New Framework. That is, you must retargetted the above 3 tasks using the SingleFrameMeasurementTask which resides in lsst.meas.base.sfm.
