   <abstract xml:lang="ru">
    <p>В статье обсуждается методика автоматической калибровки радиоизображений солнечного диска, получаемых по данным первой очереди многоволнового Сибирского радиогелиографа (СРГ). Т-образная антенная решетка СРГ состоит из 48 антенн и работает на 32 частотах в диапазоне 4–8 ГГц. Методика реализована на языке программирования Python. Приведены примеры калибровок инструментальных значений СРГ по яркостным температурам спокойного и активного Солнца на нескольких частотах для четырех эруптивных событий: 19.06.2017, 25.07.2016, 24.04.2017 и 19.04.2017. Приведены спектры для трех событий, а также оценки яркостной температуры по потоку, углового размера волокон и меры эмиссии.</p>

    <p>We discuss the method for automatic calibration of solar radio images derived from the first stage of the multiwave Siberian Radioheliograph (SRH-48). SRH is a 48-element T-shaped radiointerferometer in the 4–8 GHz frequency range. Since the end of 2017, the number of frequencies has been increased to 32. The method is implemented in Python programming language. We give examples of calibration for SRH instrument values in brightness temperature of the quiet and active Sun at several frequencies for four eruptive events: June 19, 2017, July 25, 2016, April 24, 2017, and April 19, 2017. In conclusion, we present spectra for three events, as well as brightness temperature estimates by flux, angular size of filaments, and emission measure.</p>
