  A simple mathematical model for GRB pulses is postulated in both time and
energy. The model breaks GRB pulses up into component functions, one general
light curve function exclusively in the time dimension and four component
functions exclusively in the energy dimension. Each component function of
energy is effectively orthogonal to the other energy-component functions. The
model is a good statistical fit to several of the most fluent separable GRB
pulses known. Even without theoretical interpretation, the model may be
immediately useful for fitting prompt emission from GRB pulses across energy
channels with a minimal number of free parameters, sometimes far fewer than
freshly fitting a GRB pulse in every energy band separately. Some theoretical
implications of the model might be particularly interesting, however, as the
temporal component (e.g. the shape of the light curve) is well characterized
mathematically by the well known Planck distribution.
