IVS-R1002 / R1002 2002 January 14-15 014/17:00 - 015/17:00 Haystack correlator expt #2930 Fourfit quality code summary: 61% 7-9 2% 1-6,A-H 0% 0 (non-detection) 36% no data Gilcreek (A/Gc): OK. Matera (I/Ma): Did not observe due to antenna encoder failure. Medicina (B/Mc): ~10% of S-band scans are G codes due to RFI, mainly in channel S4. Ny Alesund (N/Ny): For the 4 scans between 014-1729 and -1736 and for the single scan 015-0146, the pcal delay jumped by ~150 ps compared with its value during the rest of the session. Fringed with normal phase cal anyway. System temperatures were higher than normal due to a dewar physical temperature of ~60 K vs. normal 20 K. Westford (E/Wf): Pcal pulse epoch jumped by 400 ns between scans 014-2355b and 014-2358, resulting in a 25 ns jump in the S-band MBD clock. Refringed all Westford S-band data before 014-2358 with new additive pcal phases to correct for the jump in pulse epoch, thereby removing the MBD clock jump. RFI in channel S4 from digital audio satellites caused G codes in ~3% of S-band scans. Snow on one section of radome caused elevated SEFD in some directions. Wettzell (V/Wz): Out for Intensive from start of session through 014-2000. $ Clocks: fmout-gps used rate Gc -6.9 -6.900 Mc -100.8 -100.707 -0.70e-12 Ny -14.3 -14.221 -0.26e-12 Wf 7.2 7.120 Wz -4.9 -4.717 -1.30e-12 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 ------------------------------------------------------------------------------ AI:X 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 211 211 AI:S 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 211 211 AB:X 2 0 0 0 0 0 0 0 15 249 0 0 0 0 0 0 2 0 0 0 268 AB:S 1 0 0 0 0 0 4 5 33 200 0 0 0 0 0 0 25 0 0 0 268 AN:X 2 0 0 0 0 0 0 0 23 327 0 0 0 0 0 0 0 0 2 0 354 AN:S 2 0 0 0 0 2 4 16 57 272 0 0 0 0 0 0 0 0 1 0 354 AE:X 3 0 0 0 0 0 0 0 12 321 0 0 0 0 0 0 0 0 0 0 336 AE:S 4 0 0 0 0 0 4 3 36 276 0 1 0 0 0 0 12 0 0 0 336 AV:X 2 0 0 0 0 0 0 1 10 230 0 0 0 0 0 0 0 0 0 38 281 AV:S 0 0 0 0 0 0 2 2 18 220 0 0 0 0 0 0 1 0 0 38 281 IB:X 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 435 435 IB:S 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 435 435 IN:X 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 322 322 IN:S 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 322 322 IE:X 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 258 258 IE:S 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 258 258 IV:X 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 429 429 IV:S 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 429 429 BN:X 1 0 0 0 0 1 2 0 24 363 0 0 0 0 0 0 0 0 1 0 392 BN:S 1 0 0 0 0 2 3 16 75 258 0 0 0 0 1 0 35 0 1 0 392 BE:X 1 0 0 0 0 0 0 0 27 275 0 0 0 0 0 0 1 0 0 0 304 BE:S 3 0 0 0 0 0 1 3 49 212 0 0 0 0 0 0 36 0 0 0 304 BV:X 1 0 0 0 0 0 1 0 4 419 0 0 0 0 0 0 0 0 1 68 494 BV:S 1 0 0 0 0 1 1 0 54 310 0 0 0 0 0 0 58 0 1 68 494 NE:X 3 0 0 0 0 1 0 0 13 306 0 0 0 0 0 0 0 0 2 0 325 NE:S 4 0 0 0 0 0 0 5 34 275 0 0 0 0 0 0 5 0 2 0 325 NV:X 2 0 0 0 0 2 2 2 15 316 0 0 0 0 0 0 0 0 0 56 395 NV:S 2 0 0 0 0 2 2 14 47 272 0 0 0 0 0 0 0 0 0 56 395 EV:X 0 0 0 0 0 0 0 0 22 241 0 0 0 0 0 0 0 0 0 42 305 EV:S 2 0 0 0 0 0 1 2 14 234 0 0 0 0 0 0 10 0 0 42 305 ------------------------------------------------------------------------------ Totals 37 0 0 0 0 11 27 69 582 5576 0 1 0 0 1 0 185 0 11 3718 10218
