Simulated cone basic analysis
=============================
Simple workflow for analyzing a deflector scan data.
The same workflow can be applied in the case of manipulator angular scans.
"""
# %%
# Import the "fundamental" python libraries for a generic data analysis:
import numpy as np
# %%
# Import the navarp libraries:
from navarp.utils import navfile
# %%
# Load the data from a file:
file_name = r"nxarpes_simulated_cone.nxs"
entry = navfile.load(file_name)
# %%
# Plot a single slice
# Ex: scan = 0.5
scan = 0.5
entry.isoscan(scan).show()
# %%
# Fermi level determination
entry.autoset_efermi(energy_range=[93.8, 94.3])
entry.plt_efermi_fit()
print("Fermi level = {:.3f} meV".format(entry.efermi))
print("Energy resolution = {:.0f} meV".format(entry.efermi_fwhm*1000))
print("hv = {:g} eV".format(np.squeeze(entry.hv)))
# %%
# Since now the Fermi level is known, the same plot is automatically aligned
# Ex: scan = 0.5
scan = 0.5
entry.isoscan(scan).show()
# %%
# Plotting iso-energetic cut
# Ex: isoenergy cut at ekin = efermi
ebin = 0
debin = 0.005
entry.isoenergy(ebin, debin).show()
