1 = shot gathers 2 = CMP gathers
length, origin, and sampling of shots axis along x (if itype =2 reversed with ny3)
length, origin, and sampling of shots axis along y (if itype =2 reversed with nx3)
length, origin, and sampling of receiver axis along x
length, origin, and sampling of receiver axis along y
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
[0] stagger every other line by half in-line shot spacing
offset_azimuth in decimal degrees (itype==2)
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)
Make TRACE HEADERS for simple Marine Geometries both in CMP and SHOT GATHERs sorts
