@mbluj, thank you for the confirmation. Tau HPS DM finding selection is not applied online because it would require dedicated tuning. So tau with the worst quality is expected to...

Hi @makortel. By "succeed", do you mean just to finish without crashing, or the outputs are always identical? Especially for other taggers that use TF. In the past, we couldn't...
