multilayer_witness_measured

esis.flights.f1.optics.gratings.materials.multilayer_witness_measured()

Load a measurement of the reflectivity of the witness samples.

Measured by Eric Gullikson.

Examples

Load the measurement and plot it as a function of wavelength.

import matplotlib.pyplot as plt
import astropy.visualization
import named_arrays as na
from esis.flights.f1.optics import gratings

# Load the witness sample measurements
multilayer = gratings.materials.multilayer_witness_measured()
measurement = multilayer.efficiency_measured

# Plot the measurement as a function of wavelength
with astropy.visualization.quantity_support():
    fig, ax = plt.subplots(constrained_layout=True)
    na.plt.plot(
        measurement.inputs.wavelength,
        measurement.outputs,
        ax=ax,
        axis="wavelength",
        label=multilayer.serial_number,
    )
    ax.set_xlabel(f"wavelength ({ax.get_xlabel()})");
    ax.set_ylabel("reflectivity");
    ax.legend();
