AETC is a tool to simulate images of astrophysical objects obtained with any combination of telescope, instrument and given passband using a suitable set of parameters that define the configuration of the equipment used for the observations. The tool provides count rates and its distribution over the focal plane, through the proper definition of the PSF, of virtually any telescope equipped with an imager provided that its configuration is assessed. Moreover detailed simulation of the observed fields can be simulated including stars, galaxies and more complex objects providing image templates of the targets.
Example - 1 Simulated stellar field of the stellar population of a disk galaxy as observed by E-ELT and MICADO in J band (FoV shown is 2 arcsec). (see Greggio, L. Falomo, R. Zaggia, S., Fantinel, D. , Uslenghi, M., 2012 PASP Vol 124 pp 653 for details)
Example - 2 Simulated image of a spiral galaxy at z = 1 as observed by E-ELT and MICADO. Composite J,H and Ks color image.
