IVS-R1055 / R1055 2003 January 27-28 027/17:00 - 028/17:00 Haystack correlator expt #3009 Fourfit quality code summary: 88% 7-9 4% 1-6,A-H 1% 0 (non-detection) 7% no data Gilcreek (A/Gc): OK. HartRAO (J/Hh): OK. Matera (I/Ma): Missed first 50 minutes of session while testing was in progress to find cause of loss of fringes in recent experiments. Cause was eventually traced to a problem with the GPS clock used to measure the formatter time, and it was identified just in time to include Matera fully in the correlation. High system temperatures due to a dewar problem. ~8% of S-band scans are G or H codes due to RFI principally in channels S1 and S2. First 3 scans of pass 9 on first tape were partially overwritten by a later pass. Seshan (C/Sh): Deleted top two X-band channels in fringing due to low sensitivity in these channels. Even with the two channels deleted, 7% of X-band scans are G codes. Tigoconc (O/Tc): Five scans missed due to antenna problems. ~18% of X-band scans are G or H codes due to intermittently high (above 1000 K in some cases) system temperatures in channels X5-X8. Westford (E/Wf): Missed first part of session while dewar was being cooled. First scan observed was 027-1842. Dewar was fully cooled by 027-2045. Missed six scans from 027-1935 to 027-1955 due to antenna servo problem. Second pass on second tape largely overwritten by a later pass. ~3% of S-band scans are G or H codes due to RFI from digital audio satellites, principally in channel S4. Wettzell (V/Wz): Out for Intensive from 027-1825 to 027-1936. $ Clocks: fmout-gps used rate Gc -10.1 -10.100 Hh -6.7 -6.612 -1.27e-12 Ma 2048. 2049.143 -1.69e-12 Sh 6.4 6.186 0.30e-12 Tc --- 0.018 Wf 8.1 8.016 Wz -1.7 -1.491 0.10e-12 Processing factor = 2.9 (higher than normal because Matera fringes were detected only after the first 8 hours had been correlated, at which point the Matera scans during the first 8 hours were recorrelated) Fourfit quality/error code distribution by baseline and frequency: Qcodes 0 1 2 3 4 5 6 7 8 9 A B C D E F G H N - Tot ---------------------------------------------------------------------------- JO:X 1 0 0 0 0 0 0 0 10 32 0 0 0 0 0 0 6 1 0 1 51 JO:S 1 0 0 0 0 0 0 0 2 47 0 0 0 0 0 0 0 0 0 1 51 JE:X 2 0 0 0 0 0 1 2 25 30 0 0 0 0 0 0 1 0 0 5 66 JE:S 0 0 0 0 0 0 0 1 5 51 0 0 0 0 0 0 3 1 0 5 66 JA:X 1 0 0 0 0 0 0 0 2 11 0 0 0 0 0 0 0 0 0 0 14 JA:S 2 0 0 0 0 0 0 0 3 9 0 0 0 0 0 0 0 0 0 0 14 JI:X 1 0 0 0 0 0 0 3 29 112 0 0 0 0 0 0 0 0 0 6 151 JI:S 2 0 0 0 0 0 0 5 42 75 0 0 0 0 0 0 17 4 0 6 151 JC:X 2 0 0 0 0 0 0 1 22 28 0 0 0 0 0 0 3 0 0 0 56 JC:S 4 0 0 0 0 0 0 2 8 42 0 0 0 0 0 0 0 0 0 0 56 JV:X 2 0 0 0 0 0 3 1 25 94 0 0 0 0 0 0 0 0 0 8 133 JV:S 0 0 0 0 0 0 0 2 14 105 0 0 0 0 0 0 4 0 0 8 133 OE:X 6 0 0 0 0 0 0 0 11 57 0 0 0 0 0 0 13 2 0 10 99 OE:S 6 0 0 0 0 0 0 2 0 80 0 0 0 0 0 0 0 1 0 10 99 OA:X 4 0 0 0 0 0 0 1 2 24 0 0 0 0 0 0 4 1 0 0 36 OA:S 3 0 0 0 0 0 0 0 0 33 0 0 0 0 0 0 0 0 0 0 36 OI:X 2 0 0 0 0 0 0 0 3 27 0 0 0 0 0 0 7 1 0 1 41 OI:S 5 0 0 0 0 0 0 0 5 30 0 0 0 0 0 0 0 0 0 1 41 OC:X 0 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 0 0 1 OC:S 0 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 0 0 1 OV:X 3 0 0 0 0 0 0 1 5 21 0 0 0 0 0 0 10 0 0 2 42 OV:S 3 0 0 0 0 0 0 0 1 36 0 0 0 0 0 0 0 0 0 2 42 EA:X 1 0 0 0 0 0 0 0 21 245 0 0 0 0 0 0 0 0 2 28 297 EA:S 1 0 0 0 0 0 3 2 25 233 0 0 0 0 0 0 5 0 0 28 297 EI:X 0 0 0 0 0 0 0 0 37 167 0 0 0 0 0 0 1 0 1 21 227 EI:S 5 0 0 0 0 0 0 0 23 169 0 0 0 0 0 0 6 3 0 21 227 EC:X 1 0 0 0 0 0 0 1 43 20 0 0 0 0 0 0 19 0 0 7 91 EC:S 2 0 0 0 0 0 0 0 1 81 0 0 0 0 0 0 0 0 0 7 91 EV:X 1 0 0 0 0 0 0 1 20 207 0 0 0 0 0 0 0 0 3 33 265 EV:S 2 0 0 0 0 0 0 3 13 202 0 0 0 0 0 0 10 1 1 33 265 AI:X 1 0 0 0 0 0 0 0 9 169 0 0 0 0 0 0 2 0 2 10 193 AI:S 2 0 0 0 0 0 1 5 17 148 0 0 0 0 0 0 7 1 2 10 193 AC:X 3 0 0 0 0 0 0 0 88 95 0 0 0 0 0 0 6 0 1 0 193 AC:S 3 0 0 0 0 0 1 0 10 178 0 0 0 0 0 0 0 0 1 0 193 AV:X 0 0 0 0 0 0 2 0 11 210 0 0 0 0 0 0 0 0 0 12 235 AV:S 0 0 0 0 0 0 1 1 25 192 0 0 0 0 0 0 4 0 0 12 235 IC:X 2 0 0 0 0 0 0 1 31 72 0 0 0 0 0 0 11 0 0 6 123 IC:S 3 0 0 0 0 0 0 0 12 101 0 0 0 0 0 0 1 0 0 6 123 IV:X 3 0 0 0 0 1 1 1 23 289 0 0 0 0 0 0 0 0 1 36 355 IV:S 0 0 0 0 0 0 0 4 71 211 0 0 0 0 0 0 31 1 1 36 355 CV:X 2 0 0 0 0 0 0 2 38 78 0 0 0 0 0 0 2 0 0 8 130 CV:S 1 0 0 0 0 0 0 0 4 116 0 0 0 0 0 0 1 0 0 8 130 ---------------------------------------------------------------------------- Totals 83 0 0 0 0 1 13 42 736 4129 0 0 0 0 0 0 174 17 15 388 5598
