General Comments. ( Brief data summary and scan listing )
ES062B had 9 EVN stations Cm, Ef, Jb, Mc, Nt, On, Tr, Wb and Ys. Data from Tr was not correlated (because of 1MHz LO offset), Cm was replaced by Da and On missed the first two hours of observations. The data rate was 32 Mbps (2 x 0.5 MHz IFs, two polarizations, two-bit sampling, oversampling x 4). Only the first baseband was correlated, with cross-pols and 512 frequency points. Additional information can be found in the cover letter which is also available from the archive (see "Standardplots"). In the pipelining, the target source 'DR21(OH)N' was calibrated using the calibrators '3C286', '3C48', '3C84', 'J2007+4029' and 'J2202+4216'. The solution interval used for FRING was 1 minute. Please note however that FRING found almost no solutions for the target source. No detection for 3C48 (see also ES062A). This pipeline reduction used AIPS version 31DEC09. Ef was used as the reference antenna. This experiment followed ES062A which also had similar observing setup.

The EVN reliability indicator (ERI) for this experiment was ERI = 0.74 . ERI* = 0.74 . (Da=1, Ef=1, Jb=1, Mc=1, Nt=1, On=0.8, Tr=0, Wb=1, Ys=1)
