surfsread: Load VELOCIraptor groups in SURFS N-body simulation

In obreschkow/simstar: Reading, processing and visualising astrophysical N-body simulation data

Description

Dedicated function to load halos in cosmological N-body simulations, identified by the VELOCIraptor halo-finder. Requires the external tool surfsuite, available at https://github.com/obreschkow/surfsuite.

Usage

surfsread(
  haloid = 1,
  subhalos = TRUE,
  snapshot = 199,
  at = NULL,
  parameterset = "L210_N1024-Hydro3D"
)

Arguments

haloid	halo index in the VELOCIraptor output
subhalos	options specifying whether subhalos should be included (only works, if the specified VELOCIraptor output contains substructure)
snapshot	simulation snapshot index
at	optional snapshot index, specifying at what snapshot the particles of the halo extracted from snapshot "snapshot" should be displayed
parameterset	parameterset name; must be matched by a parameterset name in the parameterfile.txt in the path.surfsuite directory. This parameterset name specifies the actual N-body simulation, as well as the VELOCIRAPTOR output.
