quadcube

Python library (written in rust) that currently provide one method pix2vec for converting between quadcube res15 pixel number to ecliptic unit vectors.

The code is a reimplementation of parts of the COBE DIRBE map binning routines provided by A.J. Banday. See the COBE Explanatory Supplement for more information.

Install

pip install quadcube

Example

import quadcube

quadcube.pix2vec(98477345)
# >>> array([[0.37147827],

#           [0.6888555 ]])

pixels = [315879751, 238749305, 408302824, 290970621, 427780527]
quadcube.pix2vec(pixels)
