Analysis involving angular momentum.

Functions

align(h, vec_to_xform[, disk_size, ...])	Reposition and rotate the ancestor of h to place the angular momentum into a specified orientation.
ang_mom_vec(snap)	Calculates the angular momentum vector of the specified snapshot.
ang_mom_vec_units(snap)	Deprecated alias for ang_mom_vec
calc_faceon_matrix(angmom_vec[, up])	Calculate the rotation matrix to put the specified angular momentum vector face-on.
calc_sideon_matrix(angmom_vec[, along])	Calculate the rotation matrix to put the specified angular momentum vector side-on.
faceon(h, **kwargs)	Reposition and rotate the ancestor of h to place the disk face-on (i.e. into the x-y plane).
sideon(h, **kwargs)	Reposition and rotate the ancestor of h to place the disk edge-on (i.e. into the x-z plane).
spin_parameter(snap)	Return the spin parameter lambda' of a centered halo
