synthpop.modules.extinction.maps_from_dustmaps

Extinction maps collected from the dustmap module (Green, 2018)

Extinction form (i.e. reference wavelength / color excess) depends on map used.

Publication DOI: 10.21105/joss.00695

Before using this module you need to fatch the data once. See https://dustmaps.readthedocs.io/en/latest/installation.html

Bases: synthpop.modules.extinction._extinction.ExtinctionMap

Extinction maps from dustmaps

Attributes

dustmap_namestring: name of the map from dustmaps to use. options are “bayestar”, “bh”, “chen2014”, “csfd”, “decaps”, “gaia_tge”, “iphas”, “leike_ensslin_2019”, “leike_2020”, “edenhofer2023”, “lenz2017”, “marshall”, “pg2010”, “planck_gnlc”, “planck”, “sfd”
dist_2d=0.0float: if a 2-d map is applied, this sets the distance [kpc] where the extinction is applied as a single infinitely thin screen

Methods

extinction_in_map(l_deg, b_deg, dist):: estimates extinction for a list of star positions

extinction_map_name = 'dustmaps.None'

is_3D

kwargs

query

ref_wavelength

A_or_E_type

eff_wavelengths

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
