FTP Fringe Test
Selected results from the JIVE SFXC software correlator
14 June 2025
Mode:
5 cm, 128 Mbps, 8 BBC channels, 4 MHz filters, 2-bit sampling.
Participating antennas:
Jodrell Mk2 (Jb), Irbene 16m (Ib), Sardinia (Sr).
With 2 s integration times on J2202+4216.
Notes:
-- Main goal is to test the Sardinia M-band receiver with scans on J2202+4216 and W3(OH).
-- This is also a short observation request to map the currently flaring maser in G85.410+0.003.
-- Sardinia has nice fringes. The problem before was a faulty cable.
-- Irbene has no fringes. Restarted dbbc2 and synced-up multiple times, but couldn't figure out the issue. To be investigated further.
-- Maser scan auto-correlations for Sardinia (30s integrations): all detected. Middle peak (out of three) in G85 is the new flare.
