Codes of VERA telescopes whose data were available. MZ: Mizusawa; IR: Iriki; OG: Ogasawar; IS: Ishigakijima.

Number of detected maser features in the image cube created through self-calibration (⁠|$N^{\rm \ sc}_{\rm f}$|⁠) and that created through the phase-referencing (⁠|$N^{\rm \ pr}_{\rm f}$|⁠).
