By default, this will use the following spectra:
2000 ASTM Standard Extraterrestrial Spectrum Reference E-490-00

To use a different spectra, specify the `filename` when initialising the class.

Input:
filename: Filename of the solar irradiance spectrum
dlambda:
Delta wavelength: the step in wavelength defining the resolution on
which to integrate/convolute.
filename: Filename of the solar irradiance spectrum (default: 2000 ASTM)
options:
dlambda:
Delta wavelength: the step in wavelength defining the resolution on
which to integrate/convolute.
Default is 0.005 if 'wavespace' is 'wavelength' and 2.0 if 'wavenumber'.
wavespace:
It is possible to specify if the solar irradiance spectrum should
be given in terms of wavelength (default) or in terms of
wavenumber. If the latter is desired 'wavespace' should be set to
'wavenumber'.
