Is the tray correction being applied to the raw SQUID readings (before
volume correction)? It should be.

Also, is the correct run number being picked for the tray reading?
-- that is, the most recent one before the datum for which the correction
is needed. I see some odd behaviour when toggling the tray correction for
the tray samples themselves.

Tray corrections are applied after volume correction -- but since
tray correction is only available for discrete samples, and since
for discrete samples volume correction is the same in each axis,
it makes no difference whether the tray correction is applied before
or after it. The run number is no longer relevant since we've moved
to a sequential model of tray corrections, with the tray measurement
in the same file as the sample measurements.
