Addendum to ``Multichannel Kondo screening in a one-dimensional   correlated electron system''
  This is an addendum to our previous work cond-mat/9705048 (published in Europhysics Letters 41, 213 (1998)), clarifying the construction of the two-particle scattering matrices used for studying the magnetic impurity behavior in a multichannel correlated host.
