Transform the ancestor snapshot so that the provided snapshot is centred |
|
Computes the shape of a halo as a function of radius by fitting homeoidal shells. |
|
Determine the center of the halo by finding the shrink-sphere-center near the potential minimum |
|
Return the center according to the shrinking-sphere method of Power et al (2003) |
|
Recenter the snapshot on the center of mass velocity inside a sphere of specified radius |
|
Calculate the virial radius of the halo centered on the given coordinates. |
