Notes.

^(a)

Start time of observation.

^(b)

Number of ALMA 12 m antennas.

^(c)

Minimum and maximum projected baseline separations.

^(d)

On-source integration time.

^(e)

Bandpass (B), amplitude (A), and phase (P) calibrators. The calibrators are: 1: B1730-130, 2: J1700-2610, 3: Neptune, 4: Titan, 5: J1744-3116.

^(f)

Offset of the continuum peak position of Sgr B2(N1) with respect to the phase center, in equatorial coordinate system (J2000). Measurement sets with Δα differing from 0.1′′ by more than 0.2′′ (marked with a ⋆) are believed to be affected by an astrometric problem.
