✦ Synopsis

Use is made of computer simulated turbulent signals to calculate the rms of the velocity cone angle. The calculation compares favourably with X-probe data close to the axis of a circular jet. In this flow, the vector cone angle can exceed 90 ~ even on the axis. As a consequence, the rms values of the cone angle and of the lateral velocity fluctuation can be seriously underestimated with a 90 ~ Xprobe. Support for this is provided by measurements with a 120 ~ X-probe.
