+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.
