Our library doesn't get Physics Essays here either, and there probably
wouldn't be much anybody could say without the raw data.  But I do
have one good explanation for data that show a 24-hour cycle but not
a one-year cycle: systematic error.  There are plenty of things in the
average physics department that could vary on a 24-hour cycle.
Or, if he really is analyzing shift w.r.t. some fixed angle in
the lab, there might be some fixed thing in the setup that would do it.

Beware of reanalyzing data to find new effects, anyway; remember
the "fifth force."
