The presence of a period was detected using the Lomb-Scargle 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 artefacts; 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 100d, most of which are rotation periods. The final catalogue includes 1978 periods, with 1727 of them identified as rotational periods, 169 as pulsations and 82 as orbital periods of binary systems. Description: We initially selected from the CoRoT data base (Archive of the CoRoT Data Center at Space Astrophysics Institute, Orsay, France, http://idoc-corot.ias.u-psud.fr/) observations of dwarf stars (labelled as luminosity class V) with colour index B-V between 0.44 and 1.4 performed during the LRa01 and LRc01 runs of the exoplanet field (the luminosity class and colour information are from both the EXODAT/COROTSKY data base and the archive of the CoRoT Data Center).
