MemoryBackend

class beast.physicsmodel.helpers.gridbackends.MemoryBackend(lamb, seds=None, grid=None, cov_diag=None, cov_offdiag=None, header={}, aliases={})[source]

Bases: beast.physicsmodel.helpers.gridbackends.GridBackend

Instanciate a grid object that has no physical storage

Helps to create new grids on the fly. Because it derives from ModelGrid, this can be exported on disk too.

Parameters
lambndarray or str or GridBackend subclass

if ndarray - 1D float wavelength of the SEDs (requires seds and grid arguments) if str - filename of grid on disk if backend - ref to the given grid

sedsndarray, optional

2D float array of seds

gridastropy.Table, optional

table of properties associated to each sed

cov_diagndarray, optional

2D float array (# models, # filters) of the diagonal elements of the absolute flux covariance matrix

cov_offdiagndarray, optional

2D float array (# models, # elements) of the off diagonal elements of the absolute flux covariance matrix

headerdict, optional

if provided, update the grid table header

aliasesdict, optional

if provided, update the grid table aliases
