Synopsis
        sfawefd2d < file_wav.rsf vel=file_vel.rsf sou=file_src.rsf rec=file_rec.rsf > file_dat.rsf wfl=file_wfl.rsf den=file_den.rsf verb=n snap=n expl=n dabc=n cden=n adj=n fsrf=n optfd=n fdorder=4 hybridbc=n sinc=n jsnap=nt jdata=1 nqz=sf_n(az) nqx=sf_n(ax) oqz=sf_o(az) oqx=sf_o(ax) dqz=sf_d(az) dqx=sf_d(ax)
2Nth order in space, 2nd order in time
with optimized FD scheme option and hybrid one-way ABC option
