abstract = "In this paper we present the results of a coherent narrow-band
search for continuous gravitational-wave signals from the Crab and
Vela pulsars conducted on Virgo VSR4 data. In order to take into
account a possible small mismatch between the gravitational-wave
frequency and two times the star rotation frequency, inferred from
measurement of the electromagnetic pulse rate, a range of 0.02 Hz
around two times the star rotational frequency has been searched
for both the pulsars. No evidence for a signal has been found and
95% confidence level upper limits have been computed assuming both
that polarization parameters are completely unknown and that they
are known with some uncertainty, as derived from x-ray
observations of the pulsar wind torii. For Vela the upper limits
are comparable to the spin-down limit, computed assuming that all
the observed spin-down is due to the emission of gravitational
waves. For Crab the upper limits are about a factor of 2 below the
spin-down limit, and represent a significant improvement with
respect to past analysis. This is the first time the spin-down
limit is significantly overcome in a narrow-band search.",
