Example of degradation with lower spatial resolution of shock wave Tb signature from the 3D Bifrost numerical model. (a) Synthetic brightness temperature map with a cell size of ∼0.066″ averaged over the frequencies of ALMA band 3 at t = 1052 s. The white cross marks the location of the selected event, (x, y) = (9.26, 9.72) Mm. (b) The synthetic brightness temperature map degraded to the spatial resolution of the ALMA band 3 observations by convolution with the clean beam of observational data. The FWHM of the clean beam is marked by the white ellipse for reference. (c) Time evolution of the brightness temperature of the original and convolved maps at the selected location between t = 920 s and 1200 s. The vertical and horizontal dotted lines mark the Tb excess amplitude and lifetime of the shock wave signature in the respective resolution.
