SpectralGrid¶

class beast.physicsmodel.grid.SpectralGrid(*args, **kwargs)[source]¶

Generate a grid that contains spectra. It provides an access to integrated photometry function getSEDs

Parameters:

*args and **kwargs are directly forwarded to the backend constructor

lamb: ndarray or str or GridBackend

if ndarray: wavelength of the SEDs (requires seds and grid arguments) if str: filename to the grid if backend: ref to the given grid

seds: ndarray[dtype=float, ndim=2]

array of seds

grid: eztable.Table

table of properties associated to each sed

header: dict

if provided, update the grid table header

aliases: dict

if provided, update the grid table aliases

backend: str or GridBackend class or subclass

corresponding backend class

‘memory’: MemoryBackend, ‘cache’: CacheBackend, ‘hdf’: HDFBackend, ‘generic’: GridBackend

Methods Summary

`applyExtinctionLaw`(self, extLaw[, inplace])	Apply an extinction law to the model grid
`getSEDs`(self, filter_names[, absFlux, …])	Extract integrated fluxes through filters

Methods Documentation

applyExtinctionLaw(self, extLaw, inplace=False, **kwargs)[source]¶

Apply an extinction law to the model grid

Parameters:	extLaw: extinction.ExtinctionLaw apply extinction law if provided inplace: bool if set, do not copy the grid and apply on it **kwargs extra keywords will be forwrded to extLaw
Returns:	g: ModelGrid instance or None if not inplace, returns a new ModelGrid instance. Otherwise returns nothing

getSEDs(self, filter_names, absFlux=True, extLaw=None, inplace=False, filterLib=None, **kwargs)[source]¶

Extract integrated fluxes through filters

Parameters:

filter_names: list: list of filter names according to the filter lib or filter instances (no mixing between name and instances)
absFlux:bool: returns absolute fluxes if set
extLaw: extinction.ExtinctionLaw: apply extinction law if provided
inplace:bool: if set, do not copy the grid and apply extinction on it
filterLib: str: full filename to the filter library hd5 file
**kwargs extra keywords will be forwrded to extLaw

Returns:
