A range table was a list of angles of elevation a particular artillery gun barrel needed to be set to, to strike a target at a particular distance with a projectile of a particular weight using a propellant cartridge of a particular weight.
English: Table for range estimation showing target sizes, distances and corresponding angular measurments. Angular sizes are given in milliradians (mrad), ranges in meters, and target sizes are shown in both in centimeters, millimeters and inches.
The range of W 0 is inside the C-shaped black curve. The range of each of the other branches is a band between two black curves that represent points on the negative real axis (a black curve representing the positive real axis runs through the middle of each such band).

Historically, this table has been referred to as a "drop table." The drop table can be generated empirically using data taken by the shooter at a rifle range; calculated using a ballistic simulator; or is provided by the rifle/cartridge manufacturer. The drop values are measured or calculated assuming the rifle has been zeroed at a specific range.
Early in World War II, target range and bearing measurements were taken over a period of time and plotted manually on a chart. [14] The speed and course of the target could be computed using the distance the target traveled over an interval of time. During the latter part of World War II, the speed of the target could be measured using radar data.

From January 2008 to December 2012, if you bought shares in companies when James S. Crown joined the board, and sold them when he left, you would have a -2.5 percent return on your investment, compared to a -2.8 percent return from the S&P 500.
The moving ranges involved are serially correlated so runs or cycles can show up on the moving average chart that do not indicate real problems in the underlying process. [ 2 ] : 237 In some cases, it may be advisable to use the median of the moving range rather than its average, as when the calculated range data contains a few large values ...
