Igram interferes two co-registered complex images. The equation used is:
out_amp = sqrt(in1_amp * in2_amp);
out_phase = in1_phase - in2_phase;
The input files are complex (.cpx), but the output files are polar (.amp and .phase).
Igram is usually called by register_ccsd or register_sic, but can be run alone.
