Wideband image of T CrB obtained from a joint MTMFS deconvolution of all our ALMA 12 m array data on the target (bands 1 – 8) from 2024 as listed in Table 1. The size of the synthesized beam (angular resolution) is given by the ellipse plotted in the lower left corner. The parameters (major axis, minor axis, and position angle) are 1.62 arcsec, 1.16 arcsec, and 19.8°, respectively. The image resembles that of the PSF. The object is detected with 15σ significance but there are no resolved spatial features. ALMA was tracking the object at all times taking into account its proper motion. The spatial coordinates shown are those for 10 August 2024, the start of the observations.
