Fix some bugs - orbit and hlzsaa were switched in one place; there was a space in a redirection clause, which resulted in a 1 being appended to a command line; pass in the orbit series name, not the fds series name, to ingestIrisOrbit.pl; was searching through the fds series for an obsdate instead of obsdate_index (use timeslot to get the index value); add the unit field to the ingested keyword.
