The australia_gravity.csv file contains a set of gravity observations over
Alice Spings, Australia.
The data points where obtained through a block-reduction of a large compilation
of gravity observations over Australia (Wynne, 2018; Uieda, 2021).
The original dataset is available in
10.6084/m9.figshare.13643837
under a Creative Commons Attribution 4.0 International

while the instructions to download and load it using Pooch are in
https://github.com/compgeolab/australia-gravity-data.
The _prepare_australia_data.ipynb notebook downloads the original dataset,
crops it to the Alice Springs region and block reduce the data points using
blocks of 5 arc minutes.
It finally stores the resulting observations in the australia_gravity.csv
file.
