Notes. Uncertainties on the position (relative to PDS 70) are taken as 1/10 the clean beam major axis, in natural weights. ^(a)For Band 9 we show a measurement of the intensity of the peak in a region centred on its expected position. ^(b) Offset along right ascension. ^(c) Offset along declination.
