* Constants used to communicate in the second stream passed between
27
* GrAtscFSCorrelator, GrAtscEqualizer and GrAtscFieldSyncMux. The
28
* second stream is sample-for-sample parallel with the streaming
29
* floating point in the first stream. The second stream provides
30
* information about alignment boundaries.
31
*
32
* These are in floating point because the current implementation
33
* requires that for a given module, all input streams share the same
34
* type and all output streams share the same type. We'd use unsigned
35
* char otherwise.
