Notes.

(a)

Array used for observation. EVN: Effelsberg (Germany), phased-up Westerbork (5 stations, Netherlands), Jodrell-Bank (United Kingdom), Onsala (Sweden); VLBA (USA): Los Alamos (NM), Kitt Peak (AZ), St. Croix (VI), Mauna Kea (HI), Hancock (NH), Brewster (WA), Fort Davis (TX), North Liberty (IA), Pie Town (NM), Owens Valley (CA); Ar: Arecibo (Puerto Rico).

(b)

Experiment code,

(c)

observing frequency,

(d)

observing time. For the VLBI experiment, this represents the total on-source time of the whole array.

(e)

Polarization: dual means that two polarization were used (LL and RR),

(f)

bandwidth (of each IF),

(g)

number of channels in a single band or IF,

(h)

channel width in frequency.
