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. +DROP_CHANNELS Hh Ho Kk Mc SR4U SR6U Ny XR8L Tc Wf +MANUAL PCAL Kk Ho +CHANNELS Channels: XR1U = band|polarization|channel#|sideband XR1U/L BBC01 8212.99 XR2U BBC02 8252.99 XR3U BBC03 8352.99 XR4U BBC04 8512.99 XR5U BBC05 8732.99 XR6U BBC06 8852.99 XR7U BBC07 8912.99 XR8U/L BBC08 8932.99 SR1U BBC09 2225.99 SR2U BBC10 2245.99 SR3U BBC11 2265.99 SR4U BBC12 2295.99 SR5U BBC13 2345.99 SR6U BBC14 2365.99 +CLOCKS Clocks: Haystack Station fmout-gps Used rate Comments [usec] [usec] [sec/sec] Hh 1.14 1.680 0.200e-12 Ho 5.61 -2.081 -0.060e-12 -8 usec fm offset Kk 5.86 6.850 -0.120e-12 Mc -4.05 -11.921 -0.290e-12 -8 usec fm offset Ny 24.14 24.357 1.250e-12 Tc 0.62 0.890 -0.190e-12 Wf 28.28 28.747 -17.070e-12 Date: 2013/07/23 +QCODES Qcodes 0 1 2 3 4 5 6 7 8 9 A B C D E F G H N - Tot ------------------------------------------------------------ JM:X 68 0 0 0 0 0 0 0 12 24 0 0 0 0 1 0 0 0 0 0 105 JM:S 62 0 0 0 0 0 0 1 9 32 0 0 0 0 0 0 1 0 0 0 105 JN:X 19 0 0 0 0 0 0 0 2 17 0 0 0 0 0 0 1 0 0 0 39 JN:S 13 0 0 0 0 0 0 0 2 24 0 0 0 0 0 0 0 0 0 0 39 JE:X 22 0 0 0 0 0 0 0 5 20 0 0 0 0 0 0 0 0 0 0 47 JE:S 22 0 0 0 0 0 0 0 1 24 0 0 0 0 0 0 0 0 0 0 47 JH:X 58 0 0 0 0 0 1 2 3 13 0 0 0 0 0 0 0 0 0 0 77 JH:S 41 0 0 0 0 0 0 0 0 35 0 0 0 0 0 0 1 0 0 0 77 JK:X 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 JK:S 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 JO:X 6 0 0 0 0 0 0 0 0 16 0 0 0 0 0 0 0 0 0 0 22 JO:S 1 0 0 0 0 0 0 0 0 21 0 0 0 0 0 0 0 0 0 0 22 MN:X 29 0 0 0 0 0 1 1 3 76 0 0 0 0 0 0 1 0 0 1 112 MN:S 18 0 0 0 0 0 0 1 16 75 0 0 0 0 0 0 1 0 0 1 112 ME:X 43 0 0 0 0 0 0 1 10 65 0 0 0 0 0 0 0 0 0 0 119 ME:S 39 0 0 0 0 0 0 1 14 65 0 0 0 0 0 0 0 0 0 0 119 MH:X 21 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 21 MH:S 18 0 0 0 0 0 0 0 0 3 0 0 0 0 0 0 0 0 0 0 21 MK:X 21 0 0 0 0 0 0 0 0 19 0 0 0 0 0 0 0 0 0 0 40 MK:S 9 0 0 0 0 0 0 0 3 27 0 0 0 0 0 0 1 0 0 0 40 MO:X 4 0 0 0 0 0 0 0 1 5 0 0 0 0 0 0 0 0 0 0 10 MO:S 3 0 0 0 0 0 0 0 0 7 0 0 0 0 0 0 0 0 0 0 10 NE:X 24 0 0 0 0 0 0 3 8 97 0 0 0 0 0 0 1 0 0 1 134 NE:S 24 0 0 0 0 0 0 0 3 104 0 0 0 0 0 0 2 0 0 1 134 NH:X 16 0 0 0 0 0 0 0 5 4 0 0 0 0 0 0 0 0 0 0 25 NH:S 12 0 0 0 0 0 0 0 1 12 0 0 0 0 0 0 0 0 0 0 25 NK:X 19 0 0 0 0 0 1 0 2 48 0 0 0 0 0 0 0 0 0 1 71 NK:S 14 0 0 0 0 0 0 1 2 53 0 0 0 0 0 0 0 0 0 1 71 NO:X 3 0 0 0 0 0 0 0 0 7 0 0 0 0 0 0 0 0 0 0 10 NO:S 2 0 0 0 0 0 0 0 0 8 0 0 0 0 0 0 0 0 0 0 10 EH:X 3 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 0 0 4 EH:S 1 0 0 0 0 0 0 0 0 3 0 0 0 0 0 0 0 0 0 0 4 EK:X 42 0 0 0 0 1 1 1 0 54 0 0 0 0 0 0 0 0 0 0 99 EK:S 17 0 0 0 0 0 0 0 4 77 0 0 0 0 0 0 1 0 0 0 99 EO:X 4 0 0 0 0 0 0 0 3 19 0 0 0 0 0 0 0 0 0 0 26 EO:S 1 0 0 0 0 0 0 0 0 25 0 0 0 0 0 0 0 0 0 0 26 HK:X 59 0 0 0 0 0 0 4 1 30 0 0 0 0 1 0 0 0 0 0 95 HK:S 8 0 0 0 0 0 1 1 15 70 0 0 0 0 0 0 0 0 0 0 95 HO:X 1 0 0 0 0 0 0 0 2 16 0 0 0 0 0 0 0 0 0 0 19 HO:S 0 0 0 0 0 0 0 0 1 18 0 0 0 0 0 0 0 0 0 0 19 KO:X 0 0 0 0 0 0 0 0 0 9 0 0 0 0 0 0 0 0 0 0 9 KO:S 0 0 0 0 0 0 0 0 0 9 0 0 0 0 0 0 0 0 0 0 9 ------------------------------------------------------------ Totals 767 0 0 0 0 1 5 17 128 1232 0 0 0 0 2 0 10 0 0 6 2168 Legend: QC = 0 Fringes not detected. = 1-9 Fringes detected, no error condition.
