COMB: Compact embedded object simulations

COMB provides functionality to support the simulation on the sphere of compact objects embedded in a stochastic background process of specified power spectrum. Support is provided to add additional white noise and convolve with beam functions.

Functionality to support functions defined on the sphere is provided by the S2 code.

COMB is typically used with the S2FIL code to generate template functions for the construction of optimal filters, such as the directional matched filter (MF) and scale adaptive filter (SAF) on the sphere, and to general simulated data with which to test object decection algorithms.
