Functions

filter_radial_field_weighted(Br, phi, theta, ...)

Apply local weighted filtering to radial magnetic field map.

process_config(config[, method_used])

Process a single-date or multi-date Yaroslavsky configuration.

process_magnetogram_date(config, target_date)

Process one target date with the local weighted filter.
coconut_tools.magnetogram.Yaroslavsky_filter.filter_radial_field_weighted(Br, phi, theta, alpha_factor, Rn, sig=0.0, write_gaussian_prepass=False)[source]

Apply local weighted filtering to radial magnetic field map.

Parameters:

  • Br (np.ndarray) – Input magnetic field map.

  • phi (np.ndarray) – 1D array of longitudes in radians.

  • theta (np.ndarray) – 1D array of latitudes in radians.

  • alpha_factor (float) – Alpha controlling kernel sharpness.

  • Rn (float) – Radius of neighborhood in physical units.

  • sig (float) – Sigma of optional Gaussian smoothing.

  • write_gaussian_prepass (bool) – Whether to export Gaussian-smoothed version.

Returns:

Filtered Br field.

Return type:

np.ndarray
