Selecting the "mc" variation as Paul described will return tables of MC
constants, assuming the MC-specific tables have been added.  If not, the
default tables will be returned (presumably with constant values
appropriate for data).

There's not currently any way to automatically use different algorithms for
data and MC, as far as I'm aware.  In principle, one could check to see if
the selected variation is "mc" or something else, and use that to select
different algorithms, data tags, or something like that, but I'm not sure
if that's something we want to allow.


Cheers,
Sean
