// Class AliSignal
-// Handling of ALICE (extrapolated) signals.
+// Generic handling of (extrapolated) detector signals.
+//
+// The user can decide to store either calibrated or uncalibrated signals.
+// Via the specification of a gain and offset or/and an explicit
+// (de)calibration function both calibrated and uncalibrated signals
+// can always be obtained. For details see the documentation of the
+// memberfunction GetSignal() and the class AliAttrib.
+// The explicit specification of a (de)calibration function offers the
+// maximum flexibility and also allows automatic indication whether
+// calibrated or uncalibrated data has been stored.
+// The latter can be achieved by only specifying a calibration function
+// (and no de-calibration function) in case uncalibrated data is stored,
+// whereas in case of stored calibrated data the user should only
+// provide a de-calibration function (and no calibration function).
