X-ray Cluster Constraints on Non-Gaussianity

Code for evaluating the non-Gaussian mass function

These files contain C code which evaluates the series in equation 2.9 of the paper below for the hierarchical and feeder scalings (equations A.13 and A.14).

• • hierarchical.c

  • feeder.c

The result in sum should be multiplied by the Gaussian mass function to obtain the non-Gaussian one. The variables referenced here should be initialized as follows:

Note that this is C, so the indices of a size N array run from 0 to N-1. Some of the arrays are bigger than strictly necessary to keep the indices from becoming confusing (e.g. M[0], M[1] and M[2] are not used).
