Updating the background time profile

[jasonfan1997]

Not sure whether we want to add that but right the background time profile is fixed when the self.ent model is built.

This can be done by a function like

self.background_time_profile = background_time_profile
self._grl = grl
self._grl_rates = self._grl['self.ents'] / self._grl['livetime']
self.signal_time_profile = inject_signal_time_profile
start, stop = self.background_time_profile.range
return_stop_contained = True
background_run_mask = self._contained_run_mask(
start,
stop,
return_stop_contained=return_stop_contained,
)
background_grl = self._grl[background_run_mask]
self._n_background = background_grl['self.ents'].sum()
self._n_background /= background_grl['livetime'].sum()
self._n_background *= self._contained_livetime(
start,
stop,
background_grl,
)

is there a good use case for that? if so, no problem

[jasonfan1997]

Only when user trying to inject and a different background time window(like Liz's analysis? But our code doesn't config for that kind of analysis anyway).Right now maybe what Michael mentioned would be better(allowing save and load splines instead of loading event models directly)
