\n======= INPUTS ============
\n
\np0plus.rsf: initial downgoing wavefield
\n
\nREFL_000.rsf: Fourier transform of the reflection response
\n
\n======= PARAMETERS ========
\n
\nconj = [y]/n\t- complex-conjugation of the first input (corresponds to time-reversal in time)
\nverb = y/[n]\t- verbosity flag
\ntwin = y/[n]\t- returns the timewindow as one of the outputs (window=window.rsf)
\npandq = y/[n]\t- pandq=true: returns p and q, pandq=false returns Gp and Gm
\nGtot = y/[n]\t- Gtot=true returns G=Gp+Gm
\nHtot = y/[n]\t- Htot=true returns H=Gp-Gm
\nniter = 1\t\t- number of iterations
\nnshots = 1\t\t- number of shots in the reflection response
\nscale = 1.0\t- scale factor (often due to resampling)
\neps = 1e-4\t\t- threshold for the timewindow
\nshift = 5\t\t- shift in samples for the timewindow
