Constant spectral model#
This model takes a constant value along the spectral range.
\[\phi(E) = k\]
Example plot#
Here is an example plot of the model:
from astropy import units as u
import matplotlib.pyplot as plt
from gammapy.modeling.models import ConstantSpectralModel, Models, SkyModel
energy_bounds = [0.1, 100] * u.TeV
model = ConstantSpectralModel(const="1 / (cm2 s TeV)")
model.plot(energy_bounds)
plt.grid(which="both")
