STATION COMMENTS
----------------
FORTALEZA > normal
GILCREEK  > normal
HARTRAO   > Problems with telescope control first hour of observations
            get lost. Due to the phasecal unit failure the station has
            phasecal problems during the whole experiment.
TIGOWZL   > normal
            the recorded tape had high parity errors
            During the last 4 hours the receiver LO showed unlock occasionally.
            Receiver temperature  was uncontrolled, good temperature
            during the last 12 hours.
WESTFORD  > normal
            Missed data when antenna was down: 318/ 14:56 - 15:21
            RFI were affected in the highest S-band frequency channels.
            reason of the seen strong interference in S-band last freq..

WETTZELL  > normal
            Due to the acu failure following scans were lost:
            319/ 03:26 - 04:20  and 319/09:11

CORRELATION / REFRINGE
----------------

Reprocessed: Several scans with Westford have been re-correlated.
Strong interference in S-band for Westford.
Refringed:  Manual phasecal used for HartRAO
