Description:
How to display a value stored in a seismic trace header location as a mappable
Seismic Statistic?   

Solution:
You must modify the SEG-Y file before you load it into IESX.  You have to modify
the SEG-Y header trace data to put the value you want to display, into a
location that the Mappable Seismic Statistics will save and generate a graph of.
This has to be done prior to loading the seismic data and GF 3.X is not capable
of doing this, However another GeoQuest product that can do it is the 
Panther suite of Utilies for SEG-Y Data handling.

The following are the locations that are read and stored:


Statistic                              Byte location
--------------------------------------------------------
CDP_Fold per trace                        33 -  34
CDP_elevation per trace                   41 -  44
CDP_Datum per trace                       53 -  56
Water Bottom Depth per trace              65 -  68
CDP Weathering Velocity per trace         91 -  92
Time of First Sample per trace           109 - 110
