The columns =in_type=, =in_states=, =in_edges=, =in_transitions=,
=in_acc=, and =in_scc= are only output if one of the translator
produces Rabin or Streett automata (i.e., if =%D= is used to specify
one output filename for any translator). In that case these columns
give the type (DRA or DSA) of the produced automaton, as well as its
size (states, edges, transitions, number of acceptance pairs, and
number of SCCs). This input automaton is then converted by =ltlcross=
into a TGBA before being checked the result of other translators, and
all the following columns are measures of that converted automaton.
(Aside from parsing them and converting them to TGBA, Spot has no support
for Rabin automata and Streett automata.)
=states=, =edges=, =transitions=, =acc= are size measures for the
automaton that was translated. =acc= counts the number of acceptance
sets. When building (degeneralized) Büchi automata, it will always be
=1=, so its value is meaningful only when evaluating translations to
