cen_galaxy: Centering the galaxy.

In kateharborne/SimSpin: SimSpin - A package for the kinematic analysis of galaxy simulations

Centering the galaxy.

Description

The purpose of this function is to centre the galaxy such that the origin of the system lies at (0,0,0).

Usage

cen_galaxy(part_data)

Arguments

part_data

A data.frame describing the particles ID, positions, velocities and masses.

Value

A list containing the input data.frame with positions and velocities centered, as well as the median coordiantes and velocities of the original distribution

Examples

  galaxy_data = data.frame("ID"=1:100, "x"=stats::rnorm(100),
                           "y"=stats::rnorm(100), "z"=stats::rnorm(100),
                           "vx"=stats::rnorm(100), "vy"=stats::rnorm(100),
                           "vz"=stats::rnorm(100), "Mass"=rep(1,100))
  centered_galaxy = cen_galaxy(galaxy_data)
