1 year ago Laundal and Richmond, 2017 is the best all-around reference I've found for this topic, but it's quite long and detailed and a short overview or summary of the relevant parts may be helpful. This may be related to the discussion on #12 about creating a jupyter notebook tutorial for how to properly work with the Apex base vectors. @asreimer and @klaundal, did anything every come of this?
Requested feature
It would be nice to have a 'background' section in the documentation that briefly discusses the different coordinate systems, what uses they're good/bad at, and how the secular variation is treated in each of them.
The problem or gap this feature will address
It can be confusing to start using magnetic coordinates, especially when there are so many options.
The desired solution
Add a chapter to the docs. Include this reference:
Quoting @ljlamarche in #115: This article was helpful for understanding what exactly the secular variation code was trying to do. https://earth-planets-space.springeropen.com/articles/10.1186/s40623-021-01507-z
Possible alternatives
Include a section with just useful references for future reading
