pypeit.coadd1d module

Coadding module.

class pypeit.coadd1d.CoAdd1D(spec1dfiles, objids, spectrograph=None, par=None, sensfile=None, debug=False, show=False)

Bases: object

coadd()

Dummy method overloaded by sub-classes

Returns

four items

• wave

• flux

• ivar

• gpm

Return type

tuple

classmethod get_instance(spec1dfiles, objids, spectrograph=None, par=None, sensfile=None, debug=False, show=False)

Superclass factory method which generates the subclass instance. See __init__ docs for arguments.

load_arrays()

Load the arrays we need for performing coadds.

Returns

• waves, fluxes, ivars, gpms, header

Return type

tuple

run()

Runs the coadding

save(coaddfile, telluric=None, obj_model=None, overwrite=True)

Generate a OneSpec object and write it to disk.

Parameters

• coaddfile (str) – File to output coadded spectrum to.

• telluric (numpy.ndarray) –

• obj_model (str) –

• overwrite (bool) – Overwrite existing file?
