Summary

Description
English: Top panel: a mosaic MeerKAT image of the galactic center at 20 cm with a 4 resolution (Heywood et al. 2022). Bottom panel: similar to top but filtered image with a 6farcs4 resolution (Yusef-Zadeh et al. 2022a). The units are reported in Jy beam−1, where the beam area is that of the original 4 beam. The filtering process reduces the numerical value of the brightness in filament pixels by a factor of ∼0.13, with large variations due to the effect of the background removal. This factor is not applied to the filtered image intensities. Supernova remnants and H II regions identified as red circles in both top and bottom panels are excluded in the analysis.
