orphics

A Library for Theory and Analysis for Cosmology

Installation

To install:

pip install -e .

Usage

Some key modules include:

1. orphics.cosmology : Cosmology theory modules (mostly interfaces with CAMB), Limber approximated theory, etc.
2. orphics.maps : extensions to pixell and other map utilities for power spectra, ILC, etc.
3. orphics.io : plotting, config files, file i/o
4. orphics.stats : statistics, binning
5. orphics.mpi : MPI helpers
6. orphics.catalogs : galaxy catalogs, galaxy map-makers
7. orphics.lensing : CMB lensing quadratic estimator (use symlens for state-of-the-art), lensed pix-pix covariance, NFW kappa profiles, etc.

For example, if you wanted to calculate Limber approximation power spectra, you would import:

from orphics.cosmology import LimberCosmology

Known Issues

• If your interactive sessions are rudely killed by an MPI error, disable MPI by exporting the environment variable DISABLE_MPI=true as needed.
