Default quadrature rule is Keast?

Hi

Can anyone tell me what the default quadrature rule is? I thought it’d be Gauss but when I look at quadrature_schemes.py in FIAT, I saw there is default scheme as well as Gauss. Does that mean if I don’t explicitly tell to use Gauss, Keast scheme will be used? Or am I looking at wrong spot or misunderstanding something?

Sorry for this might-be-stupid question. I tried to look at ufl/measure.py, but metadata’s initilization is hard to understand, so if anyone knows the details, any reply would be appreciated.

Thanks,
Victor
