The comments below for Ny Alesund have been modified from the original report. IVS-R1176 / R1176 2005 May 23-24 143/17:00 - 144/17:00 Haystack correlator expt #3101 Fourfit quality code summary: 67% 7-9 0% 1-6,A-H 1% 0 (non-detection) 31% no data Gilcreek (A/Gc): Missed one scan due to antenna going into mechanical pre- limits. HartRAO (J/Hh): OK. Ny Alesund (N/Ny): Did not observe due to lack of notification from the IVS Coordinating Center; Ny Alesund was not included in the session station list in the IVS master schedule. Onsala (S/On): Missed 11 scans due to antenna amplifier failures. Three S-band G codes due to RFI in channel S2. Tsukuba (T/Ts): Did not record lower sidebands of channels X1 and X8. X-band closure multiband delays for station triangles involving Ts are biased typically by 20-40 ps. Data transferred via eVLBI to Mark 5 recording. Westford (E/Wf): Missed one scan due to pointing problem. -20 dBc spurious signals in several S-band channels. Eleven S-band G codes due to RFI in channel S4. Rain during most of session degraded X-band sensitivity. Wettzell (V/Wz): Scheduled outage for Intensive from 143-1800 to 143-2000. Except as noted, all stations recorded on Mark 5A. Inaccurate a priori source coordinates for NGC6251 caused multiband delay ambiguity errors on Tsukuba baselines in some scans. $ Clocks: Haystack Station fmout-gps Used rate Comments [usec] [usec] [sec/sec] Gc -8.2 -8.200 0.00 Reference Hh -1.0 -0.996 0.27e-12 On 31.8 31.653 1.13e-12 Ts 0.2 1.076 0.09e-12 Wf 9.9 9.619 0.00 Wz -15.2 -15.192 0.10e-12 Date: 05/05/23 Processing factor = 1.4* Processed in two passes due to late arrival of HartRAO and Tsukuba disk modules.
