These columns are only output if \f(CW%D\fR appears in any command
specification, i.e., if any of the tools output some Streett or Rabin
automata. In this case \fBin_type\fR contains a string that is either
\f(CWDRA\fR (Deterministic Rabin Automaton) or \f(CWDSA\fR
(Deterministic Streett Automaton). The other columns respectively
give the number of states, edges, transitions, acceptance pairs, and
strongly connected components in that automaton.

\fBstates\fR, \fBedges\fR, \fBtransitions\fR, \fBacc\fR
The number of states, edges, transitions, and acceptance sets in the
translated automaton. Column \fBedges\fR counts the number of edges

an edge labeled by \f(CWtrue\fR will be counted as 2^3=8 transitions if
the automaton mention 3 atomic propositions.
If the translator produced a Streett or Rabin automaton, these columns
contains the size of a TGBA (or BA) produced by ltlcross from that
Streett or Rabin automaton. Check \fBin_states\fR, \fBin_edges\fR,
\fBin_transitions\fR, and \fBin_acc\fR for statistics about the actual
input automaton.
