lightkurve.seismology.Seismology.estimate_deltanu

Seismology.estimate_deltanu(method='acf2d', numax=None)[source]

Returns the average value of the large frequency spacing, DeltaNu, of the seismic oscillations of the target.

At present, the only method supported is based on using an autocorrelation function (ACF2D). This method is implemented by the estimate_deltanu_acf2d function which requires the parameter numax. For details and literature references, please read the detailed docstring of this function by typing lightkurve.seismology.estimate_deltanu_acf2d? in a Python terminal or notebook.

Parameters
methodstr

Method to use. Only "acf2d" is supported at this time.

Returns
deltanuSeismologyQuantity

DeltaNu of the periodogram, including details on the units and method.
