Methods

extinction_in_map():

gets extinction value from map for star positions

extinction_map_name = 'Galaxia3D'

ref_wavelength = 0.4361

ref_wavelength2 = 0.5448

A_or_E_type = 'E(B-V)'

extinction_in_map(l_deg, b_deg, dist)

Estimates the extinction for a list of star positions.

Parameters

l_deg: ndarray [degrees]

galactic longitude

b_deg: ndarray [degrees]

galactic latitude

dist: ndarray [kpc]

radial distance from the Sun

Returns

extinction_value: ndarray [mag]

extinction at each star position defined as self.A_or_E_type
