Ammosov et al. criticize the description of the calibration and performance of two detectors of the HARP apparatus, namely the TPC and the RPC system. This Rebuttal intends to answer all points raised with experimental evidence. This Rebuttal is not concerned with the claims of the performances possibly obtained by the commenters.
