Example of modelled equatorial T_B profiles of a solar map obtained adopting the ECB-model as the solar signal for SRT at 24.7 GHz (October 9, 2019), in comparison with the observed brightness profile. These plots differ in the T_By-axis scale (linear on top, logarithmic on bottom). Blue dotted line indicates the observed equatorial T_B profile of a solar map at this observing frequency with SRT, green solid line indicates the equatorial T_B profile obtained convolving the solar signal model with the GRASP original beam pattern, and red solid line indicates the modelled equatorial T_B profile obtained with a generic beam pattern with the secondary lobe characterised by A₂ = 1.2 × a₂ (where a₂ is the reference value obtained by GRASP).
