SYNOPSIS

MTTmaps <slowmodel.H x_shot= mode=0 >maps.H


INPUT PARAMETERS

stdin - sepfile
       slow(nz,nx) = slowness model
z_shot - real
        [0.] shot Z coordinate

       [0.] first shot X coordinate
dx_shot-real
       [dxo] increment in shot X coordinate
n_shot -integer
       [1] number of shots
mode -integer
       [0]  grid is stationary the shot moves across the grid
       the second output axis coordinates are absolute.
       1=grid moves with the shot, the second output axis
       coordinates are relative to the shot location.

       [d2] increment in surface coordinate (mode=0)
nxo -integer
       [n2] number of surface coordinates (mode=0)
ozo -real
       [o1] first depth level  (mode=0)
dzo -real
       [d1] depth increments (mode=0)
nzo -integer
       [n1] number of depth levels on the grid  (mode=0)
oxo -real
       [(o2-x_shot)] first offset from shot coordinate  (mode=1)
dxo -real
       [d2] increment in offset (mode=1)
nxo -integer
       [n2] number of offsets (mode=1)
ozo -real
       [o1] first depth level  (mode=1)
dzo -real
       [d1] depth increments (mode=1)
nzo -integer
       [n1] number of depth levels on the grid
n_theta-integer
       [nxo]  number of angles for the polar grid
nr -integer
       [nzo] number of radius increments for the polar grid
fmin -real
       [10] minimum frequency in estimation band
fmax -real
       [60] maximum frequency in estimation band
nf -integer
       [16] number of frequencies to use in estimation.
dt -real
       [.008] sampling to use for initial traveltime estimation


OUTPUT PARAMETERS

stdout - sepfile
      maps(nzo,nxo,3,n_shot) = output
      Green's function maps, tt/amp/phase


DESCRIPTION

  Band-limited maximum-energy Green's function maps


COMMENTS

 Default parameters calculate one shot at user specified output location.
 x_shot must be specified! The output grid will be the same as the input grid.
 When calculating multiple maps you may want to specify the other
 parameters that control the output grid relative to each shot.
 There are two modes, if mode=0 the output grid is absolute.
 If mode=1 the output grid is relative to the shot location.
