26 May 2022
Mode 18cm: 1024 Mbps, 8 BBC channels, 32 MHz filters, 2-bit sampling
Mode 21cm: 512 Mbps, 16 BBC channels, 8 MHz filters, 2-bit sampling
Jodrell2, Westerbork, Effelsberg, Medicina, Noto, Onsala85, Tianma65, Urumqi, Torun, Hart, Cambridge, Darnhall, Knockin, Pickmere, Defford.
With 2 sec integration times on J0956+2515.
Notes on missing fringes:
Onsala85 was windstowed whole session.
Noto had a
hardware failure and couldn't participate.
eMERLIN telescopes had an error
in the mode change and didn't observe the proper frequencies in the 21cm
section.
