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],

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