synthpop.modules.extinction.gums
Extinction map used in the GAIA Universe Model, DR3 version, which combines Lallement et al (2019) & Marshall (2006)
Extinction is returned as A0, total extinction at reference wavelength 5500 Angstroms

Extinction map from Gaia Universe Model Snapshot |
Module Contents
- class synthpop.modules.extinction.gums.Gums(dr=0.001, **kwargs)
Bases:
synthpop.modules.extinction.lallement.Lallement,synthpop.modules.extinction._extinction.ExtinctionMapExtinction map from Gaia Universe Model Snapshot
Attributes
- dr=0.001float
step size for extinction integration in kpc
- per_sightline=Trueboolean
calculate extinction integral once per sightline if True (faster) calculate extinciton integral individually per star if False (slower)
Methods
- gums_ext_func(l_deg, b_deg, dist):
get extinction value in combo Lallement/Marshall combo map for list of star locations
- extinction_in_map(l_deg, b_deg, dist):
equivalent to gums_ext_func
- extinction_map_name = 'GUMS'
- marshall_query
- gums_ext_func(l_deg, b_deg, dist)
Estimates the extinction for a list of star positions.
Parameters
- l_deg: ndarray [degrees]
