Skylab is a python based toolkit to perform unbinned likelihood analyses of spatial clustering on the sphere, commonly used in astroparticle physics.
Documentation of the code can be found in ./doc
This python package provides an interface to do liklelihood maximisation searches common in neutrino astronomy, but in general extendable to any clustering search. All the magic happens within the framework of numpy, scipy, and healpy.
