fcc/bcc/sc paracrystal models use the following expression:
```text
exp_qd = mp.exp(-qd**2*a/2)
return (1 - exp_qd**2) / (1 - 2*exp_qd*mp.cos(qd*b) + exp_qd**2)
```
this can behave poorly fo…

### Problem Description
I believe the state of black holes in the game currently is too weak. At the moment, we only have Sag A*, which is a beautiful sight, and is easily viewable from a safe dist…

Similarly to https://github.com/scipp/esssans/pull/143, use some code in `scippneutron.conversion.beamline` to compute `theta`. We can't just use `scattering_angles_with_gravity` because in reflectome…

I suggest adding topics such as `neutron-scattering`, `materials-science` in the About section, as explained at https://docs.github.com/en/repositories/managing-your-repositorys-settings-and-features/…

As suggested by @BobHanson, there should be standard means to distinguish between experimental and theoretical structures. This could be a property with boolean/enum values. I would suggest "MUST" lev…
