  We investigate the exercise of locally extracting the real and imaginary
parts of the four twist-2 Compton form factors (CFFs)
$\{\mathcal{H},\mathcal{E},\widetilde{\mathcal{H}},\widetilde{\mathcal{E}}\}$
which arise in the deeply virtual Compton scattering (DVCS) process $e + p
\rightarrow e + p + \gamma$. Neglecting dynamical higher-twist contributions,
we find that there are a sufficient number of DVCS observables and degrees of
freedom to extract all 8 leading quantities model-independently, exploiting the
azimuthal dependence of the absolute cross sections across all possible beam
and target polarizations at a common kinematical point in $\{Q,t,x_B,y\}$. As
an example, for typical JLab lab-frame kinematics, we simplify the reduced DVCS
observables to their dominant terms, providing a sufficient number of equations
for local determination of the twist-2 CFFs. We demonstrate the feasibility
using harmonic fitting to both cross sections and beam spin asymmetries with
both real and pseudo-data.
