ELT Imaging Exposure Time Calculator

Important Notes

There are two ELT ETCs: Imaging and Spectroscopy. Both are generic Exposure Time Calculators, which can be used to simulate different instrument setups. The interface allows to set the simulation parameters and examine interactively the model generated graphs. The ETC programs allow easy comparison of the different options relevant to an observing program and instrument development, including target information, instrument configuration, variable atmospheric conditions and observing parameters.
