[Difx-users] difxcalc number of antennas

[Adam Deller]

Thanks for the response David! I had found those two (that was my second
email) but I am still seeing a segfault after correcting all of these three
maximum-station-related variables.  Thanks for taking a look; let me know
if you turn anything else up.

Cheers,
Adam
