General Comments. ( Brief data summary and scan listing )
This part of EP068B is the correlator pass 3, with phase center at ARP299C. It had 9 stations Ef, Mc, Cm, On, Ur, Tr, Wb. Sh, and 8 16-MHz IFs, and two polarizations. There were 32 frequency points, and integration times were 2s. Considerably more information is included in the experiment's cover letter on the standard-plots portion of the EVN Archive. In the pipelining, only the phase reference calibrator was fringed and the SOLINT was taken to be the length of the scan.

The EVN reliability indicator (ERI) for this experiment was ERI = 0.97 . ERI* = 0.97 . The ERI was 0.97 The losses include No LL fringes in Tr IF 7 and 8.
