Abstract
We present the Exposure Time Calculator (ETC) in development for ANDES, the high-resolution optical-infrared spectrograph for the Extremely Large Telescope. The ETC is a tool to predict the performances of the instrument for different parameters and environmental conditions. For these reasons, it is extremely useful in several stages of the project, from the design of the instrument to the preparation of the observations.
