CLASS MANUAL
Where to find information and documentation on CLASS?

Author: Julien Lesgourgues

  • For what the code can actually compute: all possible input parameters, all coded cosmological models, all functionalities, all observables, etc.: read the file explanatory.ini in the main CLASS directory: it is a reference file where we keep track of all possible input.
  • For the structure, style, and concrete aspects of the code: this documentation; plus the slides of our CLASS lectures, for instance those from Tokyo 2014 available at

    https://www.dropbox.com/sh/ma5muh76sggwk8k/AABl_DDUBEzAjjdywMjeTya2a?dl=0

    in the folder CLASS_Lecture_slides/.

  • For the python wrapper of CLASS: at the moment, the best is the slides from these lectures, for instance following the previous link and looking into

    CLASS_Lecture_slides/lecture7_wrapper.pdf

    and into

    IPython_Notebooks

    for example of python sessions. We will expand soon the documentation on this part with a dedicated webpage.

  • For the physics and equations used in the code: mainly, the following papers:
