It extracts value of pcal that are way to high, although the pcal injection at the stations was properly done. This force us to use manual pcal for almosty all the antennas. In some cases the visibility phases in the LSBs are not alligned with respect to the USBs phases. This lead to low quality code in the fringe fitted data. The issues are known and under investigation. +STATION_NOTES FORTLEZA (Ft/b): Scans from 213-1854 to 213-1945 were missed due to power surge. KOKEE (Kk/K): Applied manual pcal. Operating on single AZ drive. NYALES20 (Ny/N): Ok. TIGOCONC (Tc/Q): Applied manual pcal (due to the malfunctioning difx pcal extraction). TSUKUB32 (Ts/T): Applied manual pcal (due to the malfunctioning difx pcal extraction). WETTZELL (Wz/V): Applied manual pcal (due to the malfunctioning difx pcal extraction). Recorded in Mark5A format. +DROP_CHANNELS Ft Kk Ny Tc Ts Wz +MANUAL PCAL Kk, Tc, Ts, Wz +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: Bonn Station fmout-gps Used rate Comments [usec] [usec] [sec/sec] Ft 0 0.58 0 Kk 4.45 5.52 -0.049E-12 Ny -13.29 -13.01 0.432E-12 Tc 0.54 0.86 -0.015E-12 Ts 0.58 1.98 0.095E-12 Wz -22.96 -22.65 -0.097E-12 2011/08/01 +QCODES Qcod 0 1 2 3 4 5 6 7 8 9 A B C D E F G H N - Tot ----------------------------------------------------------------- bK:X 0 0 0 0 0 0 0 1 13 18 0 0 0 0 0 0 0 0 1 0 33 bK:S 0 0 0 0 0 0 0 0 0 30 0 0 0 0 0 0 2 0 1 0 33 bN:X 0 0 0 0 0 0 0 1 6 30 0 0 0 0 0 0 0 0 14 0 51 bN:S 0 0 0 0 0 0 0 0 0 37 0 0 0 0 0 0 0 0 14 0 51 bT:X 2 0 0 0 0 0 0 0 3 16 0 0 0 0 0 0 0 0 5 0 26 bT:S 3 0 0 0 0 0 0 0 0 18 0 0 0 0 0 0 0 0 5 0 26 bV:X 0 0 0 0 0 1 6 4 15 37 0 0 0 0 0 0 0 0 12 0 75 bV:S 0 0 0 0 0 0 0 0 4 56 0 0 0 0 0 0 3 0 12 0 75 bQ:X 9 0 0 0 0 0 2 14 84 68 0 0 0 0 0 0 0 0 10 0 187 bQ:S 9 0 0 0 0 0 0 0 0 165 0 0 0 0 0 0 0 3 10 0 187 KN:X 1 0 0 0 0 0 0 0 13 178 0 0 0 0 0 0 0 1 5 0 198 KN:S 1 0 0 0 0 0 0 0 2 189 0 0 0 0 0 0 0 1 5 0 198 KT:X 1 0 0 0 0 0 0 1 27 276 0 0 0 0 0 0 0 0 7 0 312 KT:S 0 0 0 0 0 0 0 1 5 296 0 0 0 0 0 0 3 0 7 0 312 KV:X 2 0 0 0 0 11 89 17 23 9 0 0 0 0 0 0 0 0 4 0 155 KV:S 8 0 0 0 0 0 0 0 1 142 0 0 0 0 0 0 0 0 4 0 155 KQ:X 3 0 0 0 0 0 0 32 4 29 0 0 0 0 0 0 0 0 2 0 70 KQ:S 0 0 0 0 0 0 0 0 0 68 0 0 0 0 0 0 0 0 2 0 70 NT:X 9 0 0 0 0 0 8 1 83 287 0 0 0 0 0 0 0 0 7 0 395 NT:S 0 0 0 0 0 0 0 0 11 376 0 0 0 0 0 0 1 0 7 0 395 NV:X 0 0 0 0 0 0 0 0 8 381 0 0 0 0 0 0 0 0 17 0 406 NV:S 0 0 0 0 0 2 0 0 4 383 0 0 0 0 0 0 0 0 17 0 406 NQ:X 0 0 0 0 0 0 0 0 0 8 0 0 0 0 0 0 0 0 1 0 9 NQ:S 0 0 0 0 0 0 0 0 0 8 0 0 0 0 0 0 0 0 1 0 9 TV:X 2 0 0 0 0 0 117 2 146 35 0 0 0 0 0 0 0 0 7 0 309 TV:S 1 0 0 0 0 0 0 0 10 287 0 0 0 0 0 0 4 0 7 0 309 TQ:X 7 0 0 0 0 0 1 3 4 7 0 0 0 0 0 0 0 0 1 0 23 TQ:S 8 0 0 0 0 0 0 0 0 14 0 0 0 0 0 0 0 0 1 0 23 VQ:X 2 0 0 0 0 0 0 0 7 18 0 1 0 0 0 0 0 0 2 0 30 VQ:S 3 0 0 0 0 0 0 0 1 24 0 0 0 0 0 0 0 0 2 0 30 ----------------------------------------------------------------- Tot 71 0 0 0 0 14 223 77 474 3490 0 1 0 0 0 0 13 5 190 0 4558 Legend: QC = 0 Fringes not detected. = 1-9 Fringes detected, no error condition.
