The main EMC offline reconstruction chain consists of:  

• StEmcAdcToEMaker - This maker gets ADC values for all EMC sub detectors and applies the calibration to get the proper energy value.
• StPreEclMaker - This maker does clustering in all EMC sub detectors.
• StEpcMaker - This maker matches the clusters in EMC sub detectors to get the final EMC point.

To have this chain working properly, some others programs are necessary. The full offline reconstruction chain is shown in the schema below:

Aside from Drupal, one can also find some very old BEMC documentation at http://rhic.physics.wayne.edu/emc/
