Abstract
Millisecond pulsars (MSP) are an important subclass of rotation powered pulsars (RPP), traditionally defined as those with P
s
< 20–30 ms and B
s
≲ 1010 G. We re-examine this definition by applying Gaussian mixture model analysis to identify distinct clusters within the RPP population and find that the MSPs appear to be better demarcated by the condition
P
s
≲ 16 ms.
