Tutorials

Tutorials cover complete workflows. For short API examples, see Examples. Start with the Simple Example.

C Foundations

• GObject in C — how NumCosmo’s object system works, and how to build your own object.
• Model Fitting in C — define a model and fit it to data from C.

Python

• Bounce Adiabatic Spectrum — adiabatic spectrum from a bounce.
• Bounce Two-Fluid Spectra — two-fluid bounce spectra, including entropy perturbations.
• Cluster WL Simulation — simulating galaxy shapes with the cluster weak-lensing tools.
• Galaxy WL Mock Catalog — a mock weak-lensing galaxy catalog built from the position/redshift/shape factors.
• Halo Catalog Mock — mock halo, cluster and member catalogs.
• Sky Match — matching observations to simulations by sky position.
• Sky Match by Membership — matching by shared membership identifiers.
• Spectral Operator Matrices — the Chebyshev-to-Gegenbauer operator matrices, their band structure, and checks that they act as stated.
• Angular Power Spectrum Accuracy — choosing the tolerances that control a non-Limber \(C_\ell\), and reading the error it reports.
