The authors' main claim Good agreement is achieved if the problem of merging overlapping jets is taken into account by varying the parameter $R_{sep}$ as a function of transverse energy and rapidity.

The abstract, sentence by sentence
We have calculated jet shapes in low $Q^2$ $ep$ and $p\overline{p}$ collisions in perturbation theory at order $\alpha_s^3$ for the hard parton-parton processes. For the $\gamma p$ process resolved and direct contributions are superimposed. The dependence of the jet shapes on transverse energy, rapidity, and inner cone extension is studied. The numerical results of the calculation are compared with recent data from ZEUS at HERA and from CDF and D0 at the TEVATRON. Good agreement is achieved if the problem of merging overlapping jets is taken into account by varying the parameter $R_{sep}$ as a function of transverse energy and rapidity.
