density_unit = 'mass'

bar_ang

density(r, theta, z)

Estimates the density at the given position

Parameters

rndarray [‘kpc’]

Distance to z axis

phi_radndarray [‘rad’]

azimuth angle of the stars. phi_rad = 0 is pointing towards sun.

z : height above the galactic plane (corrected for warp of the galaxy)

Returns

rhondarray [M_sun/kpc^3 or #/kpc^3]

density at the given location, either in number density evolved mass density or initial mass density should be specified in density_unit.
