Fig. 2 is quite flat, except for single points at the beginning and end
of this million-event section. The outlier at the highest clock value is
probably the beginning of a beam trip, since L1A drops very close to
zero. The outlier at the lowest clock value is more difficult to explain,
but it looks very similar to the lone outlier in Run 1688 (which, as
HALOG 262910 shows, _does_ contain a large synchronization gap).
