General Comments. ( Brief data summary and scan listing )
X-band NME observed on 12 Feb. 2004 (session 1/2004). This experiment was recorded at 512 Mbps using 1-bit sampling to test wide band setups at the stations. Single polarisation, 256 MHz bandwidth. Disk recording failed in Jodrell Bank. The problem affected only the two headstacks experiments (mainly NMEs) during the session. Ef failed due to an LO offset. In Cm a bad track was remapped to a system track. In Wb 7 out of 16 channels produced no finges. The ratio of the expected to the observed number of good visibilities is estimated as ERI = 0.532 (Ef=0.0, Wb=0.44, Mc=1.0, On=1.0, Nt=0.6, Ur=0.94, Sh=1.0, Hh=1.0).

Note that because the 1-bit Van Vleck correction was not applied at the correlator, the amplitudes are low by a factor of 2/pi.
