Network Monitoring Experiment
Selected results from the JIVE SFXC software correlator
1 November 2024
Mode:
1.3 cm, 2048 Mbps, 16 BBC channels, 32 MHz filters, 2-bit sampling
Participating antennas:
Jodrell Bank (Jb2), Onsala (O6), Urumqi (Ur), Metsahovi (Mh), Yebes (Ys), Hartebeesthoek (Hh), Sardinia (Sr),
KVN-Tamna (Kt), KVN-Yonsei (Ky), KVN-Ulsan (Ku), KVN-PyeongChang (Kc), VERA-Mizusawa (Vm), VERA-Iriki (Vr), VERA-Ogasawara (Vo).
(VERA not in FTP FT.)
With 4 s integration times on J1801+4404 (scans 2/4), J2025+3343 (scans 6/8), J2139+1423 (scan 10), and J2203+3145 (scans 22/34).
(In the last 45 min J2157+3127 is also observed to test phase referencing, but this source is not used in the FTP FT.)
Notes:
-- Please refer to scans 22/34 for results as that is the best fringe-finder source. Disregard the others.
-- Fringes found to O6/Ur/Mh/Ys/Sr/Ky/Kc. First time fringes with the Yebes K-band ASTROREC receiver!
-- No fringes to Jb2/Kt/Ku (possibly due to weather) and Hh (possibly source too resolved/weak).
-- KVN-PyeongChang H-maser has settled, the stabilized offset is +8.17 usec (rate was set to zero).
-- VERA-Ishigaki is not taking part in the test due to a typhoon. First time EVN observations with Iriki and Ogasawara.
-- Tianma could not observe due to the same typhoon. Torun had a receiver malfunction. Effelsberg and Noto in maintenance.
-- KVN stations Tamna and Ulsan had bad weather (rain) and high Tsys (Ku~5000K, Kt~20000K). Jodrell had also bad humid weather.
