.. _LightCurve-temporal-model:

Light curve temporal model
==========================

This model parametrises a LightCurve time model.

The gammapy internal lightcurve model format is a `~gammapy.maps.RegionNDMap`
with `time`, and optionally `energy` axes. The times are defined wrt to a reference time.

For serialisation, a `table` and a `map` format are supported.
A `table` format is a `~astropy.table.Table` with the reference_time`
serialised as a dictionary in the table meta. Only maps without an energy axis can
be serialised to this format.

In `map` format, a `~gammapy.maps.RegionNDMap` is serialised, with the `reference_time`
in the SKYMAP_BANDS HDU.
