/// This is a processor for ArchTOIPipe using the Sophya Library.
/// An example of the use of it is in the file gph425_5.cc
/// 
/// The goal of this processor is to give Q and U rings
// computed with either 3 timelines coming from the
// two channels of 1 PSB and one of the channels of a second PSB,
// or with the differences of the two channels of each PSB.
// The first of these two cases can be used if one channel is out
// or order, the second one is supposed to be better when all channels
// work fine, since it fully uses the advantage of PSB's.
//  Both methods should give the same results when the 4 channels work ok.
