init(self, filename, fluxname=None, keepneg=False)
(Constructor)

source code

Create a spectrum from a file.

Parameters:

filename (string) - FITS or ASCII file containing the spectrum
fluxname (string) - Column name specifying the flux (FITS only)
keepneg (bool) - If true, negative flux values will be retained; by default, they are forced to zero

Overrides: object.__init__

Ascii files have no headers. Following synphot, this routine will assume the first column is wavelength in Angstroms, and the second column is flux in Flam.

Overrides: TabularSourceSpectrum._readASCII
