Image showing how Gemini operates across surveys with diverse pixel scales and resolutions

Caption

The same transient is shown in three surveys, with rows corresponding to Pan-STARRS (top), MeerLICHT (middle), and ATLAS (bottom). Each row presents, from left to right, the New, Reference, and Difference images. Red circles mark the expected position of the transient candidate at the centre of each stamp. All stamps are 100×100 pixels, but their angular sky coverage differs due to survey-specific pixel scales: Pan-STARRS 0.25″/pixel, MeerLICHT 0.56″/pixel, and ATLAS 1.86″/pixel. Credit: Stoppa & Bulmus et al., Nature Astronomy (2025).
