//////////////////////////////////////////////////////////////////////////////
//
//  HRich700TaskSet
//
//  This HTaskSet contains the task sets for the Rich detector.
//  It can be distinguished between "real" and "simulation" task set by
//  passing the corresponding string to the first argument of the make()
//  function. Embedding is automatically recognized by return value of
//  gHades->getEmbeddingMode(). For embedding ONLY the "real" task set
//  has to be selected, otherwise the program will finish with an error.
//
//  To control the operation of the RICH tasks, HRich700TaskSet has following
//  switches with preset default values:
//    - inoiseOn   = kTRUE;
//    - iSkipEvent = kFALSE;
//
//  The simulation of noise in HRichDigitizer behaves in pure
//  simulation differently as compared to the embedding modus.
//     * pure simulation: simulation of both correlated and random noise is ON
//     * embedding:       only simulation of correlated noise is ON
//
//  Default values can be changed by passing corresponding strings
//  to the second argument of make() function. For more details,
//  please read the documentation for this function below.
