Fisher Matrix analysis is a quick and robust way to predict how a given survey will help constrain parameters within an assumed model. It is used to compare different surveys, and to optimise an experiment for your science goals. Fisher4Cast is a modular, user-friendly package designed to produce Fisher Matrix ellipses for an arbitrary model and number of parameters. Fisher4Cast has been publically released since May 2008, and is available from Mathworks.
The image above was generated by calling Fisher4Cast repeatedly while optimising a particular obsvervational strategy designed to measure the dynamics of dark energy. The blue areas indicate good positions in redshift space to make measurements of the distance and expansion rate for the particular survey under consideration.
