Zeroth moment maps of the 268.149 GHz emission of water in U Her obtained with the mid configuration of the main array at two different epochs, 2018, Oct. 14 and 2019, Aug. 24. The emission is integrated over the −21.6 to −9 km s⁻¹ velocity range. The 2019 image has been convolved with the larger 2018 image beam shown in the lower lrft of each panel (0.″21 × 0.″18). In both maps the noise is 0.02 Jy beam⁻¹ km s⁻¹ and the 5σ emission contour is shown as a white light: contour. The map maxima are 21.6 and 1.67 Jybeam⁻¹ km s⁻¹ in 2018 and 2019), respectively. The small red contour at the image center is the 50% continuum emission from the high resolution data. Note the SW blob emission in the 2018 map (see Sect. 6.1.1).
