Observational analysis reveals facular contrast properties across solar cycles in multi-instrument photometric data, suggesting paths to resolve discrepancies in solar irradiance models.
Aims.We have analyzed the contrast of facular features identified in a large dataset of PSPT full-disk photometric images and SoHO/MDI magnetograms, obtained from 1998 to 2005. The aim of this work is to contribute to the improvement of semi-empirical atmospheric models and of irradiance studies and to understand the reasons for the controversial results of facular contrast already presented in the literature.
