bettermoments creates moment maps of spectral line data and their associated uncertainties. The command-line interface makes it as seamless as possible to make all the traditional moment maps, in addition other, oftentimes more useful, maps. In addition to the many traditional statistical moments, bettermoments contains many alternative ways collapse the cube.

The quadratic method is described in detail in Teague & Foreman-Mackey (2018) while the uncertainties associated with more typical moment maps can be found in Teague (2019).
