SYNOPSIS

        Marine_geom3d < in.H  par=   > out.H


INPUT PARAMETERS:

itype -int
       1 = shot gathers
       2 = CMP gathers
nx3,ox3,dx3-sep_standard
       length, origin, and sampling of
       shots axis along x
       (if itype =2 reversed with ny3)
ny3,oy3,dy3-sep_standard
       length, origin, and
       sampling of shots axis along y
       (if itype =2 reversed with nx3)
nx2,ox2,dx2-sep_standard
       length, origin, and sampling of
       receiver axis along x
ny2,oy2,dy2-sep_standard
       length, origin, and sampling of
       receiver axis along y
azi -real
       azimuth of the receiver axis with respect
       to the source axis
       azi=0 (same grid )
       azi=90.  xgeo=yshot,ygeo=-xshot
       az=-90.  xgeo=-yshot,ygeo=xshot
stagger-int
      [0] stagger every other line by half in-line
      shot spacing
na2,oa2,da2 -sep_standard
      offset_azimuth in decimal degrees  (itype==2)
nr2,or2,dr2 -sep_standard
      offset_radius in km (itype==2)
      (positive values)
      ( xshot = xcmp - r*cos(a)
      ( yshot = ycmp - r*sin(a)
      ( xgeo  = xcmp + r*cos(a)
      ( ygeo  = ycmp + r*cos(a)


DESCRIPTION

        Make TRACE HEADERS for simple Marine Geometries
        both in  CMP and SHOT GATHERs sorts
