Abstract

Electron Multiplying Charge Coupled Devices (EMCCDs) are used in several astronomical applications thanks to their low noise at high frame rates. Depending on the application, it can be important to estimate the sensor gain, especially since the gain can change over time or depend on operating conditions. In this article we compare five techniques that have been proposed to estimate EMCCD gain using simulated, laboratory and data collected on-sky.
