The application shows two, three or four markers: a, A, B, and b,
depending on the button you pressed under Results.
These markers can be repositioned along the trace to calculate loss,
attenuation, reflectance, and optical return loss (ORL).
You can reposition all markers by using the controls in the Markers section.
You can drag them directly from the trace display. You can also move the
markers using the left/right arrows. Selecting marker A or B will move the
a-A or B-b pair.
