Light curve temporal model

This model parametrises a lightCurve time model.

from astropy.time import Time
from gammapy.modeling.models import (
    LightCurveTemplateTemporalModel,
    Models,
    PowerLawSpectralModel,
    SkyModel,
)

time_range = [Time("59100", format="mjd"), Time("59365", format="mjd")]
path = "$GAMMAPY_DATA/tests/models/light_curve/lightcrv_PKSB1222+216.fits"
light_curve_model = LightCurveTemplateTemporalModel.read(path)
light_curve_model.plot(time_range)

YAML representation

Here is an example YAML file using the model:

model = SkyModel(
    spectral_model=PowerLawSpectralModel(),
    temporal_model=light_curve_model,
    name="light_curve_model",
)
models = Models([model])

print(models.to_yaml())

Out:
