  Yes, sop gotoField can and should complain if the axes are not working ri=
ght.
  That said, please pay close attention to the "axis init" before the
slew. That command did fail, and that would have been the most
efficient time to deal with the problem.
  But, but, but, are you saying that the STUI Status window was not
showing any errors during the slew? The TCC was clearly reporting
RotStat with an error bit set.
