epraya.Sfilter#

Sfilter(field, count, lt=51, pol=3, startl=0, endli=-1, epsilon=5 * 10**-6, plot=True)#

Applys a Savitzky-Golay filter to the count data, finds the resonant fields and peak to peak width, and generates the plots of the filtered data, its first and second integrals.

Parameters:

  • field (np.array) – Array of the magnetic field values.

  • count (np.array) – Array of the counts values.

  • lt (int) – Window length for the Savitzky-Golay filter.

  • pol (int) – Polynomial order for the Savitzky-Golay filter.

  • start (int) – Index of the first point to draw the base line.

  • endli (int) – Index of the last point to draw the base line.

  • epsilon (float) – Prominence value to mark the peaks in the plot.

  • plot (Bool) – If true, plots the graphs of the spectrum, filtred data and first and second integrals.

Returns:

  • Hpp (list) – List of the peak to peak width finded.

  • tempa (list) – Resonant fields list.

  • spc (np.array) – Filtred spectrum.

  • integ (np.array) – First integral of the spectrum.
