- harmonica.gaussian_lowpass(grid, wavelength)¶
Calculate the Gaussian low-pass of a potential field grid
Compute the Gaussian low-pass of regular gridded data using frequency domain calculations through Fast Fourier Transform.
xarray.DataArray) – A two dimensional
xarray.DataArraywhose coordinates are evenly spaced (regular grid). Its dimensions should be in the following order: northing, easting. Its coordinates should be defined in the same units.
wavelength (float) – The cutoff wavelength in low-pass filter. Its units are the same units of the
