cosmological python initial toolkit

It is a toolkit containing routines to perform common and uncommon tasks in cosmology.

Common tasks, that you can perform with this toolkit, are:

1. Simple Statistical tests

2. cosmological coordinate transformations

3. Fitting functions and functionals, with bayesian methods

4. routines to read data from .fits and .txt files

Not-so-common tasks, that you can perform with this toolkit, are:

1. Calculation of theoretical predictions of 2point correlation function, number counts, fractal dimension using the CLASS software.

2. Calculation of estimators of 2point correlation function, number counts, fractal dimension, using the cute software

The cosmology used assumes a homogeneous and isotropic universe within the ΛCDM model.

In order to use these libraries one need to download these files in their directory:

Simply do on terminal:

git clone https://github.com/lontelis/cosmopit.git

or

python3 -m pip install --index-url https://test.pypi.org/simple/ --no-deps cosmopit

python 2.7+
numpy
pylab
scipy
pyfits
iminuit (https://pypi.python.org/pypi/iminuit)
emcee (http://dan.iel.fm/emcee/current/)
pymc (https://pymc-devs.github.io/pymc/)


CLASS (software for cosmology https://github.com/lesgourg/class_public/wiki/Installation )

To install CLASS, just do:

git clone https://github.com/lesgourg/class_public.git class

import each file as:

from cosmopit import cosmology 
from cosmopit import numMath
from cosmopit import galtools

distComVol = cosmology.D_V(z=0.5)
