Network Monitoring Experiment
Selected results from the JIVE SFXC software correlator
4 June 2024
Mode:
1.3 cm, 2048 Mbps, 16 BBC channels, 32 MHz filters, 2-bit sampling
Participating antennas:
Jodrell Bank (Jb2), Effelsberg (Ef), Medicina (Mc), Onsala (O6), Torun (Tr), Metsahovi (Mh), Yebes (Ys), Hartebeesthoek (Hh), Sardinia (Sr),
KVN-Tamna (Kt), KVN-Yonsei (Ky), KVN-Ulsan (Ku), KVN-PyeongChang (Kc).
With 2 s integration times on J0854+2006 (scans 2/4/6), J1043+2408 (scan 8), and J1159+2914 (scans 10/20/30).
Notes:
-- Fringes to everyone (see scans 6 and 20 for best results).
-- First time the new Pyeongchang (Kc) station from the KVN observed with the EVN. Nice fringes!
-- Kc still has a high drift rate (~6 ps/s), due to a new H-maser clock that hasn't stabilized yet.
--> Visible in fringe-test plots: Kc clock was last centered in scan 6 (13:10UT) and by scan 30 (15:00UT,ref=Kc) the fringe drifts by ~2 lags (~30 ns).
