hrfloat [kpc]

scale height in radii

hzfloat [kpc]

scale height in height

xlfloat

transit point

flare_flag: boolean

flare_flag = False

density(r: numpy.ndarray, phi_rad: numpy.ndarray, z: numpy.ndarray) → numpy.ndarray

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.
