Filter

class kelp.Filter(wavelength, transmittance, name=None)

Bases: object

Astronomical filter object.

Parameters

wavelengthndarray

Wavelength array

transmittancendarray

Transmittance array

Methods Summary

bin_down([bins])	Bin down the filter bandpass wavelengths and transmittances (shortcut for faster integration over the bandpass).
from_name(name)	Initialize a Filter instance from the filter name.
plot([ax])	Plot the filter transmittance curve.

Methods Documentation

bin_down(bins=10)

Bin down the filter bandpass wavelengths and transmittances (shortcut for faster integration over the bandpass).

Parameters

binsint

Number of bins in the binned transmittance curve.

classmethod from_name(name)

Parameters

namestr

Name of the filter. Examples include “IRAC 1”, “IRAC 2”, “Kepler”, “TESS”, and “CHEOPS”.

plot(ax=None, **kwargs)

Plot the filter transmittance curve.

Parameters

axAxes

Matplotlib axis object

kwargsdict

Dictionary passed to the plot command

Returns

axAxes
