     On source 3C274 with all available antennas.
     The band(s) used is(are) L   band(s).

97Feb25 05:07:00
     The on-line baseline parameters for antenna(s) 1 3 14 15 20   have
     recently been updated (prior to your observing run) to correct for
     errors resulting from their recent relocations.  In the analysis of
     your data would you please check for any significant baseline
     errors especially on these antennas and let the Data Analysts (email
     - analysts@nrao.edu) know what you find when there are
     significant baseline errors.  Thank you in advance.

     Problem(s); ELEVATION DRIVE MOTOR #2 has unclearable
     MOTOR FAULT.  Antenna will be slower to reach sources
     because of this.  Observing Data:  No Effect
