  A jet algorithm must specify how to (re-)combine different partons or towers
into a single four-vector. Various recombination schemes have been used
experimentally to examine the transverse energy profile of jets in hadron
colliders. Generally, the data is insensitive to which scheme is used. However,
we argue that the recombination scheme previously used by the \DO\
collaboration is expected to have large perturbative corrections and should not
be used for the purposes of making a quantitative comparison with fixed-order
perturbation theory.
