Geometry setting

[laith...@gmail.com]

Hello all , I find that the navigation files ( SPS , else ) for my data not work or not stander formated . So I make relative  geometry by using SUSHW order 

sushw < bs.su key=sx a=2400 c=100 j=96 > bs1.su

sushw < bs1.su key=sy a=0 c=0 j=96 > bs2.su

sushw < bs2.su key=gx a=50 b=50 c=50 j=96 > bs3.su 

sushw < bs3.su key=gy a=0 b=0 c=0 j=96 > bs4.su

sushw < bs4.su key=cdp a=1175 b=25 c=25 j=96 > bs5.su

sushw < bs5.su key=offset a=2350 b=50 c=50 j=96 > bs6.su 

bs.su : my data

a= value on first trace 

b= increment with in group 

c= increment of the group

j= number of elements 

Then I tested the geometry by plot gx Vs sx use the SUCHART order. I get a graph which could represent QC for geometry. 

1. Is the geometry assumption correct ?

2. what is the possible QC for geometry in suismic unix ?

3. Is this graph which attached (or posted) correct ?
