coords2sigma

This is a small library providing functions to convert a 2D distribution of particles to a surface density, represented by a field on a grid. Cartesian (x,y) and polar coordinates (r, phi) are supported.

Functionality

• digitize 2d corrdinates and convert to surface density
• downsample an existing cartesian or polar grid (with or without logarithmic radial spacing)

Usage

Please see the example Jupyter notebook on how to use the functions.

Setup

Install the library by running

python3 -m pip install git+https://github.com/rometsch/coords2sigma
