Abstract

PLATO is an exoplanet hunting mission of the European Space Agency. It is a medium-class mission, with a launch foreseen in 2026. Its prime objective is to uncover Earth-sized planets residing in their habitable zone. The payload consists of 26 cameras with a very wide field of view. These cameras consist of a Telescope Optical Unit (TOU), aligned at ambient and characterized at the operational temperature, and a Focal Plane Array bearing the detectors and delivered after coupling with the Front End Electronics. In this contribution, we report on the methods used at TOU level to characterize Focal Plane using a Hartmann Mask, i.e. we illustrate the analysis pipeline after data collection in the cryo-vacuum chamber at Leonardo (LDO), the implementation of new algorithms, and an extended uncertainties study for the Hartmann analysis.
