- sncosmo.read_bandpass(fname, fmt='ascii', wave_unit=Unit('Angstrom'), trans_unit=Unit(dimensionless), normalize=False, trim_level=None, name=None)¶
Read bandpass from two-column ASCII file containing wavelength and transmission in each line.
File format of file. Currently only ASCII file supported.
Unitor str, optional
Wavelength unit. Default is Angstroms.
Transmission unit. Can be
dimensionless_unscaled, indicating a ratio of transmitted to incident photons, or units proportional to inverse energy, indicating a ratio of transmitted photons to incident energy. Default is ratio of transmitted to incident photons.
- normalizebool, optional
If True, normalize fractional transmission to be 1.0 at peak. It is recommended to set to True if transmission is in units of inverse energy. (When transmission is given in these units, the absolute value is usually not significant; normalizing gives more reasonable transmission values.) Default is False.
- namestr, optional
Identifier. Default is
