Notes.

(a)

Array used for observation. EVN: Effelsberg (Germany), phased-up Westerbork (Five 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 denotes 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.
