\begin{Description}\relax
This data set is from a simulation of a servo system
involving a servo amplifier, a motor, a lead screw/nut, and a
sliding carriage of some sort. It may have been on of the
translational axes of a robot on the 9th floor of the AI lab. In any
case, the output value is almost certainly a rise time, or the time
required for the system to respond to a step change in a position
set point. The variables that describe the data set and their values
are the following:

\Tabular{cll}{
[,1] & Motor & A,B,C,D,E\\{}
[,2] & Screw & A,B,C,D,E\\{}
[,3] & Pgain & 3,4,5,6\\{}
[,4] & Vgain & 1,2,3,4,5\\{}
[,5] & Class & 0.13 to 7.10
}
