General Comments. ( Brief data summary and scan listing )
This is an EVN phase-referencing, spectral line experiment at 1.3 cm (dual polarisation, single IF correlated with 1024 spectral channels). Participating stations were Cm, Ef, Jb (Mk2), On, Mc, Nt, Ur, Sh, Mh. Mc and Ur failed due to frequency setup problems and were not correlated. The reference antenna for pipeline calibration was Ef where available, otherwise Jb. Jb was chosen as the reference antenna for plotting. This experiment used 5 different frequency modes, which were pipelined separately.

The EVN reliability indicator (ERI) for this experiment was ERI=0.43 (Cm=0.98, Ef=0.5, Jb=0.98, On=0.98, Mc=0, Nt=0.98, Ur=0, Sh=0.95, Mh=0.7). ERI gives you an estimate of the ratio of observed/good visibilities to the expected number. ERI* is the same, but excludes data lost due to circumstances out of the EVN's control e.g. bad weather (ERI*=0.50, since Ef lost half of the experiment due to weather).
