Should the Background makers create their own meta info? Or, more generally, does any operation on a dataset create some meta info?

What meta information should the IRF classes have? The DL4 classes created by Gammapy can have the Creation info. They can also store info of the type of DL3 products...

CI fail is not due to #5354 ?

> All in all a method based on MC simulations might be the more natural solution, even if computationally more intensive. I think that is the solution that is being...

This would be good to sort before the 1.3 release. Shall we remove sherpa from the required dependencies and advise people to optionally install it? I recently installed the dev...

@katrinstreil Note that if you rather have `energy = np.array([1000, 3000, 5000]).reshape(-1,1)` (ie, correctly broadcasted), then your example works.

@adonath can it be made to break on `init`? That makes it easier to understand, otherwise, it seems that the `MapCoord` is created but something is funny with its shape

If you have a dataset with `energy_true = energy`, then it works for the fitting by silently creating a diagonal edisp matrix and fails in the flux estimation. I propose...

Making a note here for future reference. In the current sensitivity estimation notebook, the sensitivity curve is independent of the `on_region_radius`. By doing the energy-dependent correction for the containment, we...

Hi @bkhelifi ! @Astro-Kirsty added some info here https://docs.gammapy.org/dev/tutorials/api/estimators.html#a-fully-configured-flux-points-estimation Would it suffice to add a link from the HowTo, or would you prefer more explanations?
