Add selectional aux output
Fix track output bug

The track output was moved into tick from valout to reduce the number of
duplicated routines in the surge code.  Unfortunately the initial

the output of the track to valout, removes it from tick, and changes the
warning in the plotting from an exception to a printed warning.
