Exposure Time Calculator
We have built a pipeline to generate realistic spectro-photometric data as observed with MAAT and perform an end-to-end modelling analysis. The pipeline’s input consists of templates to model the theoretical flux of the source of interest and the relevant information for the Exposure Time Calculator (ETC). The ETC provides the output S/N (exposure time) as a function of wavelength for a requested exposure time (S/N), taking into account the transmission through the atmosphere and the telescope and instrument (MAAT+OSIRIS) optics. It works for the whole suite of OSIRIS gratings and for an optional range of source geometries. The ETC output includes the observed simulated spectra in physical units (erg/cm2/s/Å).
