Topic:
Why does my SEG-Y synthetic print as a straight line in a scaled plot?

Description:
Additional information regarding loading a SEG-Y synthetic through IESX Data
Manager in GeoFrame 3.8. If the loaded SREF has an extremely large amplitude
range, you must scale down the array values by a factor during the load.     

Solution:
Reason:
The Loaded SREF array (synthetic curve) has extremely large amplitudes.
Need to scale down the array values during the load process.

Procedure:
1. Go to Log Curves Data Manager > select object synthetic curve (SREF)
   curve > click on "i" icon (fourth from the left), and examine the amplitude
   range of the object SREF in the Log Curve Editor (max/min). 

2. IESX Session Manager > Seismic/"Load Seismic..."; In Load seismic trace          header window select "Define input format..."

3. Set Scale factor so that resultant value of largest amplitude of the SREF
   curve times the scale factor is somewhere between 0 and 1.5. OK.
   
   (For example, data loaded with an amplitude range or -65000 to +85000,
   would use the largest amplitude of 85000 times a scale factor of 0.00001
   to generate a resultant amplitude of 0.85).

4. In Load seismic trace header window > select "Load..."
