N23X2 - Network Monitoring Experiment - selected results from the JIVE SFXC software correlator
13 June 2023
Mode: 3.6 cm, 2048 Mbps, 16 BBC channels, 32 MHz filters, L+R, 2-bit
sampling.
Stations: Westerbork (Wb), Effelsberg (Ef), Medicina (Mc), Noto (Nt),
Onsala 20m (O6), Sheshan 25m (Sh),
Urumqi (Ur), Torun (Tr), Yebes (Ys), Hart
(Hh), Irbene 16m (Ib).
With 2-s integration times on
J0927+3902 (aka 4C39.25) (scans 1-8) and J1159+2914 (scans 9-14).
Notes:
-- Mc and Ys were doing parallel recordings with DBBC3.
-- Sh clocks updated from an old value to around 65 us now.
-- Ur still looks linear (same as in N23X1). Follow up on this.

Tried correlating 1 stream of the Yebes data (Yd), but I edited something
wrong in the vex file (ignore Yd column, report on it later).
