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)
<AxesSubplot: xlabel='Time [iso]', ylabel='Norm / A.U.'>
YAML representation#
Here is an example YAML file using the model:
model = SkyModel(
spectral_model=PowerLawSpectralModel(),
temporal_model=light_curve_model,

)
models = Models([model])
print(models.to_yaml())
