The aging of the instrument : II. Global efficiency
Abstract
The global efficiency of the whole chain decreases with time, due to the decrease of the electronic gain and of the optical transmission. Although the effect is clearly observed on the data, it is not possible to measure the individual contribution on the different effects. We will show how we measure the global loss of efficiency and how we correct it on the data. In particuliar, we will present the evolution of this correction according to the version of the data.
