// Class AliSignal
// 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).
+//
// Note :
// ------
// Signal positions (r) and reference frames (f) are specified via
//
// AliSignal q; // In the example below a signal contains the
// // following data : timing, ADC and dE/dx
-// q.SetName("TOF hit");
+// q.SetNameTitle("Hybrid","Test for multiple signal data");
// q.SetPosition(pos,"car");
// q.SetPositionErrors(err,"car");
// signal=82.5; // e.g. signal time in ns
// error=2.01;

// q.SetSignalError(error,1);
// q.SetOffset(offset,1);
// signal=268.1; // e.g. ADC value of signal
// error=3.75;
// gain=120.78;
-// q.SetSignal(signal,2);
-// q.SetSignalError(error,2);
-// q.SetGain(gain,2);
+// offset=1.5732;
+// // Addressing via name specification instead of index
+// q.SetSlotName("ADC",2);
+// q.SetSignal(signal,"ADC");
+// q.SetSignalError(error,"ADC");
+// q.SetGain(gain,"ADC");
+// q.SetOffset(offset,"ADC");
// signal=23.7; // e.g. corresponding dE/dx value
// error=0.48;
-// offset=0.2;
-// gain=150;
-// q.SetSignal(signal,3);
-// q.SetSignalError(error,3);
-// q.SetOffset(offset,3);
-// q.SetGain(gain,3);
