Hi Jim,
   Sorry to mislead you in the night log, but we always slew to an FK5
star and make a pointing correction at the beginning of each spectroscopic
observation.  Thsi is now the standard routine, and so it does not get
mentioned in the log.  We could not find any FK5 stars, which is why we
went to 2d magnitude stars, with the same results.
