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.
