Rotational evolution of low mass stars: The case of NGC 2264. Lamm M.H., Mundt R., Bailer-Jones C.A.L., Herbst W. <Astron. Astrophys. 430, 1005 (2005)> =2005A&A...430.1005L
ADC_Keywords: Clusters, open ; Stars, pre-main sequence ; Stars, variable ; Photometry, VRI Keywords: Galaxy: open clusters and associations: individual: NGC 2264 - Galaxy: open clusters and associations: individual: ONC - stars: pre-main sequence - stars: rotation - stars: formation Description: Table 1 lists 405 periodic variable stars we found in the area of NGC 2264 between. It contains information of the position, brightness, colours, and period of these stars. It also lists the spectral type taken from the literature (if available) as well as the alternative identification numbers of the stars which we used in the analysis process. The results presented here are based on a photometric monitoring program of a 34'x34' field in NGC 2264 carried out with the Wide-Field-Imager (WFI) attached to the ESO/MPG 2.2m telescope on La Silla, Chile. Observations were obtained on 44 nights in the IC band during a period of two months between Dec. 2000 and March 2001. We also obtained several additional images through V, RC and Hα filters.
