            SpectralElement

Base class for a Spectral Element (e.g. Filter, Detector...).

Instance Methods

[hide private]

__mul__(self, other)
Permitted to multiply a SpectralElement by another SpectralElement, or by a SourceSpectrum.

source code

__rmul__(self, other)

source code

convert(self, targetunits)
Spectral elements are not convertible.

source code

__call__(self, wavelengths)
This is where the throughput array is calculated for a given input wavelength table.

source code

taper(self)
Taper the spectrum by adding zeros to each end.

source code

writefits(self, filename, clobber=True, trimzero=True)
Write the bandpass to a FITS file.

source code

resample(self, resampledWaveTab)
Interpolate throughput given a wavelength array that is monotonically increasing and the TabularSpectralElement object.

source code

unitResponse(self)
Original implementation; correct only for the assumption that the input 'unit spectrum' is in units of photlam.

source code

calcUnitResponse(self, fluxunits='photlam')
This is a method of the spectral element for the convenience of the user, but the correct calculation of the unit response depends entirely on the units, so delegate to the fluxunit's method.

source code

calcTotalFlux(self, inSpectrum)
Moved method from obsolete Magnitude class

source code

calcVegaFlux(self)
Moved method from obsolete Magnitude class.

source code

GetWaveSet(self)

source code

GetThroughput(self)
Return the throughput for the internal wavetable

Method Details

mul(self, other)

source code

Permitted to multiply a SpectralElement by another SpectralElement, or by a SourceSpectrum. In the former case we return a CompositeSpectralElement, while in the latter case a CompositeSourceSpectrum.

unitResponse(self)

source code

Original implementation; correct only for the assumption that the input 'unit spectrum' is in units of photlam. Marked for deletion when calcUnitResponse is well tested.

calcVegaFlux(self)

source code

Moved method from obsolete Magnitude class. Definitely need to fix up Vega handling here.
