Chem-I-Calc: The Chemical Information Calculator¶
Chem-I-Calc is an open source python package for evaluating the chemical information content of resolved star spectroscopy. It takes advantage of the Fisher information matrix and the Cramér-Rao inequality to quickly calculate the Cramér-Rao lower bounds (CRLBs), which give the best theoretically achievable precision from a set of observations.
In this documentation, we hope to provide an overview of the underlying methodology and intended application of Chem-I-Calc. However, a more detailed and complete discussion of the scientific motivation, statistical foundations, and practical limitations of our methods can be found in Sandford et al. (In Press).
