This is a set of analysis tools to be used in CMB research. It currently consists of code to calculate the pure Cl power spectra from a HEALPix map along with the associated mode-mixing matrices. In addition it contains a port of polspice to Python. Finally, we have added code to calculate the COBE Quadcube pixel number given an input position on the sky.

Requirements

There are several Python modules needed in order to run this code. They are

  • Numpy
  • Scipy
  • Astropy
  • Healpy
  • Mpi4py

In addition, the location of the cmb_analysis directory needs to be added to your PYTHONPATH environment variable.
