A derived quantity I am working with (best not go into the detail) requires the use of anisotropic errors. By this I mean the positive error is a different value to the negative error:
(note the above line art is rotated by 90 degrees - the errors on bin content are “anisotropic”)
I am currently using my own class, inherited from TH1F. How do I deal with this? I can’t find anything in the documentation that does this… anyone got any pointers?
