Synchrotron emission maps for the MD model (top) and the GD model (bottom), defined in the frequency channel centered at 1115 MHz and with a bandwidth of δν ∼ 9.33 MHz (30 channels configuration). The maps are presented in celestial coordinates and were convolved with a FWHM = 40 arcmin beam. The observed region corresponds to the BINGO covered area with the apodized Galactic mask defined in Sect. 3.2.
