-// Creates and handles digits from TRD hits //
-// Author: C. Blume (C.Blume@gsi.de) //
-// //
-// The following effects are included: //
-// - Diffusion //
-// - ExB effects //
-// - Gas gain including fluctuations //
-// - Pad-response (simple Gaussian approximation) //
-// - Time-response //
-// - Electronics noise //
-// - Electronics gain //
-// - Digitization //
-// - ADC threshold //
-// The corresponding parameter can be adjusted via the various //
-// Set-functions. If these parameters are not explicitly set, default //
-// values are used (see Init-function). //
-// As an example on how to use this class to produce digits from hits //
-// have a look at the macro hits2digits.C //
-// The production of summable digits is demonstrated in hits2sdigits.C //
-// and the subsequent conversion of the s-digits into normal digits is //
-// explained in sdigits2digits.C. //
