-// Task Class for making SDigits in EMCAL
-//
+// This is a class that makes SDigits out of Hits
+// A Summable Digits is the sum of all hits originating
+// from one in one tower of the EMCAL
+// A threshold for assignment of the primary to SDigit is applied
+//
+// SDigits need to hold the energy sum of the hits, but AliEMCALDigit
+// can (should) only store amplitude. Therefore, the SDigit energy is
+// "digitized" before being stored and must be "calibrated" back to an
+// energy before SDigits are summed to form true Digits
