Field notes
The calculator accepts separate X and Y coordinates for the mortar and target, then produces range, bearing, elevation, and a sight-picture position between printed marks. Its documented envelope is 110–704 metres, and the page explains that the sight scale is uneven in metres, so it interpolates between adjacent rows instead of treating the labels as equally spaced. A sample result gives 224.0 metres, 765 mil, and a 7.7-degree bearing.
