+CORRELATOR_NOTES

Twenty category-4 GAIA sources were observed in RD1305 (see session notes).
Only 28% of the X-band observations and 53% of the S-band on these sources
were detections.  In the schedule file used at the stations, the epochs of
the 20 source coordinates were incorrect.  As a result, most antennas would
have been mispointed by of order half to a full X-band beamwidth.  The
correct coordinate epochs were used in correlation.

+STATION_NOTES

HARTRAO (Hh/J):  Transferred via e-VLBI.

HOBART26 (Ho/H): Fringed with manual phases due to absence of phase cal.
                 RFI in SR4U caused one G code.
                 Mark 5A recording transferred via e-VLBI.

KOKEE (Kk/K):    Fringed with manual phases.

MEDICINA (Mc/M): Weak fringes and phase cal in SR4U and SR6U --
                   both channels deleted in fringing.
                 RFI in SR2U caused three G codes.
                 Phase cal amplitudes changed systematically by 10-40%
                   in all X-band channels several times during session.
                   System temperatures were stable.  Phase cal phases do
                   not appear to have been affected detrimentally.
                 Mark 5A recording.

NYALES20 (Ny/N): Deleted XR8L in fringing due to low fringe amplitude.
                 Missed one scan when Mark 5B disk filled up.
                 Large phase cal phase jumps in a few scans.
                   Instability is in RF phase cal signal, not LOs.
                 X-band phase cal amplitudes in ~25 scans are >50% lower
                   than in other scans.  Amplitude loss is present on
                   one-second time scale, not just in coherent scan average.
                   Amplitude loss is smaller at S-band.
                 Unstable XR6U video converter LO in one scan caused
                   three G codes.
                 Transferred via e-VLBI.

TIGOCONC (Tc/O): OK.

WESTFORD (Wf/E): RFI in SR4U and SR5U caused three G codes.

Except as noted for individual stations, all stations recorded on Mark 5B.
