Field of view with position and 95% positional uncertainty of 2FLE J2256.8-2751 (black star), 2FLE associated 4FGL source position and 95% positional uncertainty (green diamond), the 1FLE location position and 1﹩\mathop{.}\limits^{{\unicode{x000b0}}}﹩5 positional uncertainty (orange square), and 1FLE associated 4FGL source position and 95% positional uncertainty (magenta circle). The positional uncertainties of the 4FGL counterparts are very small and, therefore, are not visible in this plot. In this instance, the 2FLE association is most likely the true one based on location alone.
