Input known variables in shaded boxes.

* If "No Match" appears beside the calculated length of curve, or the T Length, there is a bust

in the data for this curve.

Use this spreadsheet to check curve data, or to calculate curve variables based upon the

Bearings into and out of the Curve, and the known P.C., P.I., and P.T. Stations.

All units are English Units.
