Fig. 2 Chart showing where an LEE has been seen in experiments with the Oslo method. Green
stars indicate that an LEE was observed, orange circles indicate that no LEE was observed. Pink
diamonds indicate cases that are unclear with respect to the LEE
Fig. 3 A sketch of how we
picture the LEE’s evolution as
a function of mass. The
yellow curve is an LEE at low
mass, the red curve at high
mass. E γ,min indicates the
experimental threshold for
extracting the LEE
