MemoryBackend

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

Bases: 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
