HOBART26 (Ho/H): Fringed with manual phases due to absence of phase cal. RFI in SR6U -- channel deleted in fringing. X5-X8 fringe amps are ~50% weaker than X1-X4. Lowered G-code threshold from default 0.5 to 0.4, to reduce number of X-band G codes from ~55 to 7. RFI in SR5U caused seven G codes. Mark 5A recording transferred via e-VLBI. NYALES20 (Ny/N): Fringed with manual phases due to unreliable phase cal. Phase cal was highly unstable or even absent during many scans due to problem with antenna cable carrying 5 MHz to phase calibrator. Transferred via e-VLBI. ONSALA60 (On/S): Transferred via e-VLBI. SESHAN25 (Sh/C): Weak fringes in SR4U caused by strong signal at 4.01 MHz -- channel deleted in fringing. Adjusted XR7U delay by 56 ns in fourfit to correct for delay offset. WETTZELL (Wz/V): No valid data before 352-0030 due to problems with Mark4 formatter. Valid data were recorded after 352-0030 using DBBC, but they were 1-bit, not 2-bit, leading to a loss of SNR. Missed last six scans. No fringes in XR8U/L due to an error in setting up DBBC -- channel deleted in fringing. RFI in SR5U and SR6U caused three G codes. Adjusted XR5U-XR7U delays by 46 ns in fourfit to correct for delay offsets. Transferred via e-VLBI. Except as noted for individual stations, all stations recorded on Mark 5B. +DROP_CHANNELS Hh Ho SR6U Ny On Sh SR4U Wz XR8U/L +MANUAL PCAL Ho Ny +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 3.12 5.410 0.190e-12 Ho 11.90 4.152 -0.250e-12 -8 usec fm offset Ny 90.41 90.570 1.800e-12 On 4.32 6.320 0.050e-12 Sh 29.74 39.650 0.740e-12 Wz -30.08 -28.050 -0.180e-12 Date: 2015/12/17 +QCODES Qcodes 0 1 2 3 4 5 6 7 8 9 A B C D E F G H N - Tot -------------------------------------------------------------- JN:X 5 0 0 0 0 0 0 0 4 41 0 0 0 0 0 0 0 0 0 0 50 JN:S 4 0 0 0 0 0 0 0 0 46 0 0 0 0 0 0 0 0 0 0 50 JS:X 5 0 0 0 0 0 0 0 5 63 0 0 0 0 0 0 0 0 1 0 74 JS:S 7 0 0 0 0 0 0 0 1 65 0 0 0 0 0 0 0 0 1 0 74 JC:X 1 0 0 0 0 0 1 1 9 31 0 0 0 0 0 0 0 0 0 0 43 JC:S 7 0 0 0 0 0 0 0 1 35 0 0 0 0 0 0 0 0 0 0 43 JV:X 5 0 0 0 0 0 0 1 3 60 0 0 0 0 0 0 0 0 0 32 101 JV:S 11 0 0 0 0 0 0 0 1 56 0 0 0 0 0 0 1 0 0 32 101 JH:X 10 0 0 0 0 0 0 1 24 36 0 0 0 0 0 0 2 0 0 0 73 JH:S 12 0 0 0 0 0 0 0 22 36 0 0 0 0 0 0 3 0 0 0 73 NS:X 0 0 0 0 0 0 2 5 23 124 0 0 0 0 0 0 0 0 1 0 155 NS:S 29 0 0 1 0 0 0 0 1 123 0 0 0 0 0 0 0 0 1 0 155 NC:X 7 0 0 0 0 0 0 0 9 51 0 0 0 0 0 0 0 0 0 0 67 NC:S 12 0 0 0 0 0 0 1 4 50 0 0 0 0 0 0 0 0 0 0 67 NV:X 2 0 0 0 0 0 1 2 11 79 0 0 0 0 0 0 0 0 0 14 109 NV:S 14 0 0 0 0 0 0 0 1 80 0 0 0 0 0 0 0 0 0 14 109 NH:X 5 0 0 0 0 0 0 1 10 21 0 0 0 0 0 0 0 0 0 0 37 NH:S 13 0 0 0 0 0 0 0 0 24 0 0 0 0 0 0 0 0 0 0 37 SC:X 3 0 0 0 0 0 0 0 2 33 0 0 0 0 0 0 0 0 0 0 38 SC:S 12 0 0 0 0 0 0 0 1 25 0 0 0 0 0 0 0 0 0 0 38 SV:X 2 0 0 0 0 0 0 0 8 92 0 0 0 0 0 0 0 0 1 29 132 SV:S 2 0 0 0 0 1 0 0 1 96 0 0 0 0 0 0 2 0 1 29 132 SH:X 3 0 0 0 0 0 0 0 1 12 0 0 0 0 0 0 0 0 0 0 16 SH:S 6 0 0 0 0 0 0 0 1 9 0 0 0 0 0 0 0 0 0 0 16 CV:X 2 0 0 0 0 0 1 0 5 41 0 0 0 0 0 0 0 0 0 22 71 CV:S 12 0 0 0 0 0 0 0 0 37 0 0 0 0 0 0 0 0 0 22 71 CH:X 12 0 0 0 0 2 2 24 54 35 0 0 0 0 0 0 5 0 0 0 134 CH:S 27 0 0 0 0 0 1 6 16 80 0 0 0 0 0 0 4 0 0 0 134 VH:X 2 0 0 0 0 0 0 1 1 5 0 0 0 0 0 0 0 0 0 9 18 VH:S 4 0 0 0 0 0 0 0 1 4 0 0 0 0 0 0 0 0 0 9 18 -------------------------------------------------------------- Totals 236 0 0 1 0 3 8 43 220 1490 0 0 0 0 0 0 17 0 6 212 2236 Legend: QC = 0 Fringes not detected. = 1-9 Fringes detected, no error condition.
