efficiency_vs_wavelength

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

Load the measured efficiency as a function of wavelength.

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

Examples

Plot the efficiency vs wavelength 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_wavelength()

# Plot the measurements using matplotlib
with astropy.visualization.quantity_support():
    fig, ax = plt.subplots()
    na.plt.plot(
        efficiency.inputs.wavelength,
        efficiency.outputs,
        ax=ax,
        label=efficiency.inputs.time.strftime("%Y-%m-%d"),
    );
    ax.set_xlabel(f"wavelength ({ax.get_xlabel()})");
    ax.set_ylabel(f"efficiency");
    ax.legend();
