Validphys is not able to deal with PDF sets with `ErrorType: replicas+as`

Question

Closed this issue 6 months ago · 3 comments

When trying to use a PDF set that contains ErrorType: replicas+as I get the following error:

[ERROR]: Bad configuration encountered:
No Stats class for error type replicas+as

This is because such error type is not implemented in validphys, so rather
than a bug this is a feature request.

What should the expected behaviour be for the +as replica(s)?

to replicate the LHAPDF behaviour, no? see config and code here or here

In the end we decided that erroring out on this is a "feature not a bug". We want to keep parametric uncertainties (like $\alpha_s$) separated.
