Exposure Time Calculator – SIGNAL
SIGNAL calculates the number of object and sky photons which will be detected during imaging exposure of a point or extended source with one of the common-user instruments of the ARISTARCHOS telescope.
If bandwidth, extinction and sky brightness are left set at zero, SIGNAL assumes sensible defaults (click on parameter name for details).
For details of the assumptions made by SIGNAL, or to access the code, please see the SIGNAL help page, or click on a parameter name above (NB the help page may open in a separate tab).
This is version AR1.0 of SIGNAL. Last Updated: 21 Oct 2013.
