// Class AliMUONSt1ResponseParameter
// ---------------------------------
// Describes a set of filters to be applied to a digital value
// in order to simulate electronics characteristics 
// (pedestal, noise, sticky bits, etc....)
// Threshold levels for the MANU zero supression algorithm are included.
