Notes.

(a)

Calibrated using 3C286 (I = 0.39 Jy beam−1, Pl = 4.3%).

(b)

Calibrated using 3C286 (I = 0.49 Jy beam−1, Pl = 4.8%).

(c)

Calibrated using results from G23.44-0.18.

(d)

Self-noise in the maser emission channels (e.g., Sault 2012). When no circularly polarized emission is detected we consider the self-noise of the brightest maser feature.

(e)

Formal errors of the fringe rate mapping.
