Directivity form

The source directivity is set per frequency on this form. Data may be entered directly, or imported from a text file containing each entry on a separate line. To import a text file covering a given frequency, click on the File cell at the top of the column for that frequency.

90 degrees is vertically up, 0 degrees is horizontal to the source, and +90 is vertically down. Directivity is linearly interpolated between the given values where needed. Greyed-out rows indicate that the angle is outside the current range of takeoff angles set for dBSeaRay.

The directivity data is used by the dBSeaRay solver. As of dBSea version 1.0, dBSeaPE and dBSeaModes do not support source directivity.
