Cobaya: step function likelihood

[Helena Garcia]

Is it possible to add a step function in the likelihood block of the cobaya .yaml file?
For example, a gaussian when a parameter is greater than a fixed value, and 0 when the the parameter is smaller than that value. Is there any reference I can check on how to write this. Thanks!

You can add a lambda prior in the prior block as in the advanced example
