Euclid H2rg Detectors: Impact Of Crosshatch Patterns On Photometric And Centroid Errors

In the framework of ESA's Science programme, the Euclid mission [1] has the objective to map the geometry of the Dark Universe. For the Near Infrared Spectrometer and Photometer (NISP) instrument, the state-of-the-art HAWAII-2RG detectors (cut-off at 2.3 mu m) from Teledyne Imaging Systems will be used in association with the SIDECAR ASIC readout electronics. A dedicated test bench has been developed at ESA/ESTEC to test these detectors. This publication will show the impact of crosshatch patterns on photometric and centroid errors after flat field correction.
