General Comments.
This project consists of 7 stations, 2 band x 2 Pols. Ef is a reference antenna.
Tr: less than 40% of data available. Totally 10 calibrators were pipelined. Pipeline script was updated on 10 June 2002.
ERI=0.52 (Eb=0.98, Jb=0.95, Mc=0.99, Tr=0.40, Wb=0.98, On=0.85, Cm=0.98), ERI*=0.52 (artificial errors only).

both a priori and self calibration; the square of this number gives the antenna
noise (SEFD) in Jy).
