Version 0.1.1

Released on: 2020/01/10

This release contains only a documentation fix: include install instructions for conda and pip. No functionality has been changed (hence, no DOI was issued).

Version 0.1.0

Released on: 2020/01/10

Digital Object Identifier

First release of Boule including basic functionality:

  • Definition of the Ellipsoid class: based on the semi-major axis, flattening, geocentric gravitational constant, and angular velocity. Other quantities are derived from these 4.

  • Computation of normal gravity and coordinate conversions between geodetic and geocentric.

  • Ellipsoid realizations for the Earth (WGS84 and GRS80) and Mars.

Version 0.0.1

Released on: 2019/11/06

Digital Object Identifier

This release is a placeholder that serves as a marker for the start of this project. It is used to register the project on PyPI and test the continuous integration deployment process.
