epraya.Overseer

Overseer(field, counts, lt=51, pol=3, i=0, startl=0, endli=-1, epsilon=5 * 10**-6, plot=True)

Interactive function for spectrum analysis of the experimental data, applying Savitzky-Golay filter to the data, finding it’s resonant fields, peak to peak distance and first and second integral.

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:

Sdata (Class) – Container of the saved values of peak to peak widths, resonant fields, filtred spectrum and the first integral.
