Þ Can rotation smear out spectral features? 
Bow shock nebula powered by a relativistic wind of e± generated by the pulsar spin-down Þ estimate of the spin down power 

             dE/dt ~  I W dW/dt ~ 8 x1032 erg/s 
Magneto-dipolar breaking (PdP/dt »10-15B122)

dE/dt ~ 1034 (B12 t6)-2 erg/s   
Þ   B12 t6  ~ 3
Also:  no pulsations within 4% gave an allowed fraction of sky 2-4%
This fraction is even smaller with the new upper limit on the pulsed fraction of 1%
