AB: We investigate the effect of the spatial distribution of nanoflare heating on loop observables. We perform 1D time-dependent hydrodynamic simulations of nanoflares occurring at sub-resolution strands, that make up the observed coronal loops. The simulations use different spatial forms for the nanoflare heating (randomly localized, footpoint, uniform loop top). The outputs of the simulations are then used to calculate diagnostics from synthetic TRACE and SXT observations. We find that the diagnostics depend only weakly on the spatial distribution of the heating, and therefore are not especially useful for distinguishing among the different possibilities. We propose that the best way to study the field-aligned spatial distribution of nanoflare heating is to observe the very high temperature plasmas that are present only in the earliest stages of an event.
