Clock jump of ~10 ns following this gap. Hobart (H/Ho): -20 dBc spurious signal in channel X1. Tigoconc (O/Tc): X-band sensitivity reduced by warm receiver during first several hours of session, and by coherence loss caused by unstable receiver LO in many scans, particularly during second half of session. Frequent X-band LO phase jumps of 180 deg and larger. Tsukuba (T/Ts): 83 scans missed due to K5 problems. Data transferred via eVLBI to Mark5 recording. Westford (E/Wf): ~2% of S-band scans are G codes due to RFI in channel S4. Fringed S-band with manual phases due to presence of strong spurious signals in several channels. Maser was repaired during the previous week to fix an instability problem. Video converter 5 (channel X5) was replaced at 171-1732. Wettzell (V/Wz): RFI in channel S4 from 172-1219 to 172-1309, but only one G code. Scheduled outage for Intensive from 171-1812 to 171-1944. Except as noted, all stations recorded on Mark 5A. $ Clocks: Haystack Station fmout-gps Used rate Comments [usec] [usec] [sec/sec] Gc -8.4 -8.265 0.00 Ho 10.6 10.639 0.09e-12 Tc -2.8 -2.732 0.00 Ts 0.3 1.209 0.00 Wf 6.6 6.500 0.32e-12 Reference Wz -15.2 -15.127 0.00 Date: 05/06/20 Processing factor = 1.9* Processed in three passes due to late arrival of Gilcreek and Hobart disk modules.
