Query: The rotation of field stars from CoRoT data   We present period measurements of a large sample of field stars in the solar
neighbourhood, observed by CoRoT in two different directions of the Galaxy. The
presence of a period was detected using the Scargle Lomb Normalized Periodogram
technique and the autocorrelation analysis. The assessment of the results has
been performed through a consistency verification supported by the folded light
curve analysis. The data analysis procedure has discarded a non-negligible
fraction of light curves due to instrumental artifacts, however it has allowed
us to identify pulsators and binaries among a large number of field stars. We
measure a wide range of periods, from 0.25 to 100 days, most of which are
rotation periods. The final catalogue includes 1978 periods, with 1727 of them
identified as rotational periods, 169 are classified as pulsations and 82 as
orbital periods of binary systems. Our sample suffers from selection biases not
easily corrected for, thus we do not use the distribution of rotation periods
to derive the age distribution of the main-sequence population. Nevertheless,
using rotation as a proxy for age, we can identify a sample of young stars (<
600 Myr), that will constitute a valuable sample, supported by further
spectroscopic observations, to study the recent star formation history in the
solar neighborhood.
