摘要：

We present an estimate for the contribution of solar quiet network to total solar irradiance based on measurements of the brightness contrast for network and internetwork regions. These regions were identified with a numerical procedure applied on sub-arrays extracted from full-disk 1kx1k CaII K (393.3 nm), Blue (409.5 nm) and Red (607.2 nm) continuum images obtained with the PSPT telescope at the Rome Observatory. Our estimate, that results of the order of 0.01%, can be used to model long-term irradiance variations.
