These files list the strike bearing and dip angle for pairs of planes, for which you wish to compute intersection bearing and plunge using the Utilities | Planes | Beta Pairs program.
This example illustrates data entered using the Right Hand Rule format (dip direction clockwise from strike); you may also enter the planar data as dip direction and dip angle.
- Strike 1: Required. Lists the azimuth bearing of the strike of the first plane (using the Right Hand Rule format) or the bearing of the dip of the plane. For use within the Beta Pairs command, you may specify which format you are using (strike and dip OR dip direction, dip angle) prior to performing the computations.
- Dip 1: Required. Lists the dip angle of the first plane, with 0 = horizontal.
- Strike 2: Required. Lists the azimuth bearing of the strike of the second plane (or the bearing of the dip if using dip direction, dip angle).
- Dip 2: Required. Lists the dip angle of the second plane, with 0 = horizontal.
- Direction: Optional. You may include this blank column for use with the Beta Pairs program for storage of the computed direction of the lineation resulting from the intersection of the two listed planes.
- Plunge: Optional. You may include this blank column for use with the Beta Pairs program for storage of the computed plunge of the intersection lineation.
