## Detailed Description

MUON SDigitizer (from Hits to SDigits).

New sdigitizer, not deriving from MUONDigitizer, and using new Response:DisIntegrate method Note also that this one does not merge sdigits at all (this is deferred to the digitizer, which anyway has to do it), thus speeding a little bit this step.

## Member Function Documentation

 void AliMUONSDigitizerV2::Digitize ( Option_t * opt = "" )
virtual

Go from hits to sdigits.

In the code below, apart from the loop itself (which look complicated but is really only a loop on each hit in the input file) the main work is done in AliMUONResponse::DisIntegrate method, which converts a single hit in (possibly) several sdigits.

## Member Data Documentation

 Float_t AliMUONSDigitizerV2::fgkMaxIntTime = 10.0
staticprivate

maximum time of interaction

The sdigitizer performs the transformation from hits (energy deposits by the transport code) to sdigits (equivalent of charges on pad).

It does so by converting the energy deposit into a charge and then spreading this charge over several pads, according to the response function (a Mathieson distribution, basically).

See also AliMUONResponseV0, which is doing the real job (in DisIntegrate method), while this sdigitizer is just "steering" the process.

Please note that we do not merge sdigits after creation, which means that after sdigitization, a given pad can have several sdigits. This merging is taken care of later on by the digitizer(V3).
