We here examine an active region model constructed from an ensemble of simple loops placed in a dipole magnetic structure. The emission pattern in EUV and X-rays produced by the model depends sensitively on the model heating function. Of the six models tested, the most realistic emission patterns arose from heating functions with an inverse dependence on the loop volume. Both resonant heating and nanoflare heating theories predict such a dependence and therefore pass the test.
