Comment (by Giuseppe Ficarra):

In line 16th in param.ccl in ScalarBase, we should add absolute value for phi.

I don’t quite understand this comment. Line 16th in ScalarBase/param.ccl is a comment about the definition of a potential depending on the square of the scalar field. Why do we need to include the absolute value?
