Hello there,

I noticed a weird behaviour of xTensor Implode function with densities. 
Indeed, the latter do not propagate their densitites to the imploded objects. 
Please find attached a MWE file.
Did I miss any mathematical/code aspect that would justify the absence of a WeightOfTensor-> in CovDTensor1

Thanks and regards,
Joffrey

I agree with you, Joffrey. That option should be included in the private functions CovDTensor1, ParamDTensor, OverDotTensor, and LieDTensor within xTensor. In the meantime, you can always use WeightOfTensor[CD3DT] ^= AIndex after Impliding the tensor.

Best,
Juan
