efficiency_vs_angle_0deg

esis.flights.f1.optics.gratings.efficiencies.efficiency_vs_angle_0deg()

Load the measured efficiency at normal incidence as a function of output angle.

This includes contributions from both the coatings and grooves and was measured by Eric Gullikson.

Examples

Plot the efficiency vs output angle measurements using matplotlib.

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

# Load the efficiency measurements
efficiency = gratings.efficiencies.efficiency_vs_angle_0deg()

# Plot the measurements using matplotlib
with astropy.visualization.quantity_support():
    fig, ax = plt.subplots()
    na.plt.plot(
        efficiency.inputs.direction.output,
        efficiency.outputs,
        ax=ax,
        label=efficiency.inputs.direction.input,
    );
    ax.set_xlabel(f"output angle ({ax.get_xlabel()})");
    ax.set_ylabel(f"efficiency");
    ax.legend();
