pixon_sensitivity

The sensitivity in creating the pixon map. 0.0 is most sensitive, >3.0 is very insensitive. The default is 0.0, i.e. the default is to give the most structure possible in the image. If you get images with structure that you think are spurious, try increasing this parameter to 0.2 or 0.5 to eliminate the over-resolution.

The default was arrived at after much testing and simulation. Don't mess with it unless you know what you are doing. If sensitivity is set too small, you may get spurious sources; too large, and you may miss real sources.

Note: The pixon_resolution parameter can also be used to control the spatial scale of structure the pixon code will look for.
