AliITSUv0Layer(Int_t lay, Bool_t turbo, Int_t debug)
Constructor setting layer number and debugging level
for a "turbo" layer (i.e. where staves overlap in phi)
void CreateLayer(TGeoVolume* moth)
Creates the actual Layer and places inside its mother volume
Input:
moth : the TGeoVolume owing the volume structure
Output:
Return:

Updated: 08 Jul 2011 Mario Sitta
Updated: 20 May 2013 Mario Sitta Layer is Assembly instead of Tube
Local variables
void CreateLayerTurbo(TGeoVolume* moth)
Creates the actual Layer and places inside its mother volume
A so-called "turbo" layer is a layer where staves overlap in phi
User can set width and tilt angle, no check is performed here
to avoid volume overlaps
Input:
moth : the TGeoVolume owing the volume structure
Output:
Return:
