Abstract

This paper describes the damage occurring in CCDs exposed to solar radiation and explainsits implications for the Gaia measurements by focusing on the astrometric instrument. Itintroduces the strategy that will be used in the Gaia data processing to mitigate theradiation induced effects, and presents CEMGA (CTI effects Models for Gaia) amulti-purpose platform which hosts different models that simulate radiation effects onCCDs.
