Example catalogue

The public tutorials are deliberately small enough to read from top to bottom. They are not a dump of internal tests.

Notebook	Main objects	Scientific focus
quick_start.ipynb	SFCProjection, Corr_2PCF	URL catalogue, saved base field, isotropic 2PCF, and result plot
particle_io.ipynb	read_particle_data	FoF input, NPZ conversion, raw BIN layouts, and native readers
sfc_projection.ipynb	SFCProjection, SFCField	Field values, normalisation, resolution, redshift space, and metadata
window.ipynb	SFCField, WindowFunc	Field algebra, kernels, custom windows, and composition caveats
physical_fields.ipynb	weighted SFCField objects, operator windows	Velocity derivatives, momentum density, potential, and acceleration
counting.ipynb	Counting, CountingData	One-point samples, PDFs, and smoothing response
corr2pcf.ipynb	Corr_2PCF, Corr2PCFData	Isotropic and redshift-space two-point statistics
corr3pcf.ipynb	Corr_3PCF, Corr_3PCF_Multipole	Monte Carlo 3PCF, multipoles, and consistency checks

Each tutorial names the script and YAML file that generate any heavy saved product it reads. Start with the notebook to understand a workflow; move to the script and configuration when the calculation belongs on a server.
