Notes. From left to right, the columns contain the ALMA configuration and the run for duplicated observations, the observation date, the optical pulsation phase (pulsation period = 310 days; JDmax = 2457896 following AAVSO (https://www.aavso.org/)), the size and PA of the synthesised PSF, the visibility weighting (N, “natural”, means robust = 1 and U, “uniform”, robust = 0.1 in GILDAS), the maximum recoverable scale, the continuum peak for every configuration, the continuum integral above the 5σ level contours, the peak emission of the Gaussian components of the fit, and the FWHM and PA after deconvolution. When the Gaussian fit is not provided (–), the source can be considered as point-like. The errors of the continuum peak and the continuum integral do not consider the flux calibration uncertainties. The statistical errors of the Gaussian fit are always ≲5%. (a − g)The characteristic HPBWs, θPSF, are
