Wise Observatory Utilities
Signal to Noise (S/N) Calculator
The Signal to Noise calculator could be used for estimating
the exposure time needed for imaging an object with a given S/N.
The deafult values in the utility are for the Wise Observatory with the
Textronics CCD camera but one can change
this value to be usefull for other observatories and instruments.
The calculation is done for moonless night!
Systenatic errors are not taken into account (e.g. FF color, etc.).
The PSF is assumed to be a Gaussian.
