Quality control of residual and tomo statics
The module represents results of residual (Statics - Surface Consistent ) or tomo statics (Tomo Statics 2D/3D). It consists of location map for sources and location map for receivers. Color of source and receivers on a location map is defined by statics correction values. We can choose any source point from the source location map and get view of common shot gather for the chosen source before and after statics correction. Also in case of 3D data there is a graph of statics correction values for chosen source line and chosen receiver line. Use Statics azimuthal QC module for statics QC in case of getting statics from the Refraction FB picking - azimuthal solver guide / phase / aperture module.
SEG-Y data handle - input seismic gather, NMO-corrected (not strict, but reasonable), any sorting (usually CMP gather).
GStaticCorrectionItem in - Reference to static correction item.
Trace headers - Reference to sorted traces.
Imported file - define path for input static corrections.
Visualization statics on CS/CR gathers:
Visualization time - Location of statics correction graph horizontal axis.
Scale - Vertical scale for statics correction graph.
Show - If checked the graph of statics correction values is shown on common source /common receivers view.
Apply statics parameters:
MaxShift (if 0 = disabled) - Maximum shift value.
ApplySurfaceConsistent - If checked surface consistent statics will be applied.
ApplyTrim - If checked trim statics will be applied.
ApplyStructuralFactor - If checked structural factor will be applied.
Direction to move on shift - Direction to move can be Up or Down.
Fast Interpolation - If checked fact interpolation will be applied.
Trend removal:
Grid size
Smooth
Number of threads - perform calculation in the multi-thread mode.
GStaticCorrectionItem out - Static corrections.
CR gather - common receiver gather without static correction applied.
CS gather - common source gather without static correction applied.
CR gather applied - common receiver gather with static correction applied.
CS gather applied - common source gather with static correction applied.

A test seismic data set is the Poland 2D (land) line, you Poland 2D line that is accessible on the internet free or it is also included to the g-Platform installation (C: \Program Files (x86)\Geomage \gPlatform \demodata\ Poland_2D_Vibroseis_LINE_01).
