Euclid Data Release 1 (DR1): VIS processing and data products
Year: 2026
Type: preprint
Abstract: This paper describes the characteristics of the Euclid visible imager (VIS) data delivered as part of the Euclid Data Release 1 (DR1). This data set contains 42092 calibrated frames. Validated nominal exposures cover 2092 deg$^2$ of sky. We outline the minor changes made to the VIS processing function (PF) since previous releases. For the wide survey, the photometric and astrometric accuracy of the reference stellar sample $(18.5 < I_{\rm E} < 19.8)$ is excellent. The internal and external astrometric dispersions are 0.08 and 0.18 mas, respectively, at the quadrant level, and 3.4 and 5.6 mas at the source level. The corresponding internal and external photometric dispersions are 0.76 and 1.4 mmag at the quadrant level, and 11 and 25 mmag at the source level. We characterise remaining astrometric and photometric systematic effects: focal-plane-dependent variations; time-dependent photometric offsets; and colour-dependent centroid shifts. The noise floor in the deepest VIS images appears to be set by the extended diffuse light of faint galaxies. Globally, the DR1 VIS data meet pre-launch mission requirements and the 42092 images it contains provide our first substantial look at the sky as seen by VIS.
