For each $l$, let $\check{X}_{l}$ be the K3 surface given by the data $(\check{X}_{l},\check{\bf B}_{l}+i\check{\omega}_{l},\check{\Omega}_{l})$ mirror to $(X,{\bf B}_{l}+it_{l}\omega,t_{l}\Omega)$. The sequence of surfaces $\{\check{X}_{l}\}$ is said to approach a large complex structure limit point.
