FilterSystem

class artpop.filters.FilterSystem(filter_curve_files, filter_names, **kwargs)

Bases: object

Class for calculating filter parameters from throughput curves. The parameter definitions are taken from Fukugita et al. (1996) AJ 111, 1748.

Parameters

filter_curve_fileslist

List of the file names of the filter curves.

filter_namesstr

Names of filters. Must be the same length as filter_curve_files.

**kwargs

Optional argumnets for loadtxt, which is used to load the filter curve files.

Methods Summary

dlam(bandpass)	Calculate the bandpass width.
effective_throughput(bandpass)	Calculate the effective throughput for the given bandpass.
lam_eff(bandpass)	Calculate effective wavelength for the given bandpass.
lam_pivot(bandpass)	Calculate pivot wavelength for the given bandpass.
