What is the red circle and why is it not a line?

Hi Explorer15 and welcome to Higgs Hunters
The red circle is an artifact and there is no need to mark these colourful circles or ellipses as weird.
See the FAQ for more info : http://talk.higgshunters.org/#/boards/BHH0000001/discussions/DHH00000np
Happy hunting ! 😄
