amplitude_with_wavelength#

gadfly.scale.amplitude_with_wavelength(filter, temperature, n_wavelengths=10000, **kwargs)[source]#

Scale power spectral feature amplitudes with wavelength and stellar effective temperature, compared to their amplitudes when observed with SOHO VIRGO/PMO6.

Follows the Taylor expansion argument in Sect 5.1 of Morris et al. (2020), see Eqn 11 [1].

Makes use of the tynt package to retrieve filter transmittance curves. To see available filters via tynt, run:

>>> from tynt import FilterGenerator
>>> f = FilterGenerator()
>>> print(f.available_filters())
Parameters

  • filter (str or Filter) – Either the SVO FPS name for a filter bandpass available via the tynt package, or an instance of the Filter object itself.

  • temperature (Quantity) – Stellar effective temperature

  • n_wavelengths (int) – Number of wavelengths included in the calculation.

  • **kwargs (dict) – Passed on to reconstruct().

Returns

alpha – Scaling for the amplitude of intensity features relative to the SOHO VIRGO amplitudes

Return type

float
