Dear Kwant Developers, I would like to know the unit of the current density shown in the current plot. Does it always equal "unit of current/relwidth" for a 2D system? I understand that abswidth can replace relwidth. If I do not specify any abswidth, will the relwidth be replaced? Finally, the relwidth is defined as , as a fraction of the length of the longest side of the bounding box. What is the definition of the bounding box? Is it the area in which the current is plotted? Thank you in advance for your help.
