WACO Correlator Report for NA446 (exp# 8446) Obs: 13,14 Nov. 2001 doy 317/318 Correlated: 20 Nov. 2001 to 24 Nov. 2001 Exported: done 84% Qcodes 5-9 9% Qcode 0 3% Qcodes BDEFG Station notes: Kokee (K): OK manual p-cal. Algonquin (G): OK Intermittant S-band interference in last channel Fortaleza (F): missed 317-1858 -> 2025, 317-2128 -> 318-0424 : elevation motor missed all after 318-1729 : formatter problem receiver warm after 318-1537 leading to 0 quality codes Matera (I): Dropped frequency 2322.99 (f): caused G-codes almost 100% of scans. Remaining large number of G-codes due to many S-band channels affected by interferance. Ny Alesund (O): missed 317-1911 -> 1933, 317-2126 -> 2142 power outages Some missed sources not indicated in log; unprocessed scan list larger than normal Wettzell (V): OK S-band and X-band delay rate residuals show ionospheric disturbance on some baselines 64 scans (17%) reprocessed. $ Clocks: Station fmout-gps Used rate Kokee: 0.30 0.30 Algonquin: 0.69 0.94 Matera -7.55 -6.70 Fortaleza: --- 1.19 Ny Alesund: -13.80 -13.08 9.0e-13 Wettzell: -20.50 -18.46 Qcodes 0 1 2 3 4 5 6 7 8 9 A B C D E F G H N - Tot ------------------------------------------------------------------------------- GK:X 0 0 0 0 0 0 1 2 14 110 0 0 0 0 0 0 0 0 3 0 130 GK:S 0 0 0 0 0 0 0 4 17 91 0 0 0 0 0 0 15 0 3 0 130 GI:X 18 0 0 0 0 0 0 0 3 106 0 0 0 0 0 0 0 0 3 0 130 GI:S 18 0 0 0 0 0 0 3 40 48 0 0 0 0 0 0 18 0 3 0 130 GO:X 0 0 0 0 0 0 2 2 34 105 0 0 0 1 2 0 1 0 6 4 157 GO:S 2 0 0 0 0 5 13 21 35 60 0 0 0 0 2 0 9 0 6 4 157 GV:X 0 0 0 0 0 0 0 0 5 131 0 0 0 0 0 0 0 0 2 0 138 GV:S 0 0 0 0 0 0 0 1 12 105 0 0 0 0 0 0 18 0 2 0 138 GF:X 11 0 0 0 0 0 3 8 13 40 0 0 0 1 0 0 0 0 0 42 118 GF:S 12 0 0 0 0 0 0 2 11 46 0 0 0 0 0 0 5 0 0 42 118 KI:X 21 0 0 0 0 0 0 1 1 48 0 0 0 0 0 0 0 0 5 0 76 KI:S 25 0 0 0 0 0 0 3 6 36 0 0 0 0 0 0 1 0 5 0 76 KO:X 2 0 0 0 0 0 5 5 16 90 0 0 0 0 0 0 0 0 8 6 132 KO:S 2 0 0 0 0 5 4 7 20 80 0 0 0 0 0 0 0 0 8 6 132 KV:X 0 0 0 0 0 0 1 0 8 72 0 0 0 0 0 0 1 0 4 0 86 KV:S 2 0 0 0 0 0 0 0 6 74 0 0 0 0 0 0 0 0 4 0 86 KF:X 2 0 0 0 0 0 0 2 3 21 0 0 0 0 0 0 0 0 0 21 49 KF:S 5 0 0 0 0 0 0 0 2 21 0 0 0 0 0 0 0 0 0 21 49 IO:X 22 0 0 0 0 2 1 3 15 125 0 0 0 0 0 0 0 0 10 8 186 IO:S 36 0 0 0 0 0 1 6 14 106 0 0 0 0 0 0 5 0 10 8 186 IV:X 33 0 0 0 0 6 2 1 9 190 0 0 0 0 0 0 2 0 8 0 251 IV:S 37 0 0 0 0 0 0 6 62 111 0 0 0 0 0 0 27 0 8 0 251 IF:X 17 0 0 0 0 0 0 2 8 56 0 0 0 0 0 0 0 0 2 41 126 IF:S 35 0 0 0 0 0 0 1 6 40 0 0 0 0 0 0 1 0 2 41 126 OV:X 0 0 0 0 0 2 2 11 41 125 0 0 0 0 0 0 0 0 10 8 199 OV:S 3 0 0 0 0 1 5 11 29 128 0 1 0 0 0 0 3 0 10 8 199 OF:X 3 0 0 0 0 1 0 0 5 46 0 0 0 1 0 0 0 0 1 41 98 OF:S 7 0 0 0 0 0 0 0 4 45 0 0 0 0 0 0 0 0 1 41 98 VF:X 10 0 0 0 0 0 3 2 12 48 0 0 0 0 0 0 0 0 0 38 113 VF:S 12 0 0 0 0 0 0 0 5 56 0 0 0 0 0 0 2 0 0 38 113 ------------------------------------------------------------------------------- Totals 335 0 0 0 0 22 43 104 456 2360 0 1 0 3 4 0 108 0 124 418 3978 9% >--->--->82% 3% Legend: QC = 0 Fringes not detected. = 1-9 Fringes detected, no error condition.
