Catalog of Cepheids from the SMC

We present the Catalog of Cepheids from the SMC which contains data for 2049 objects detected in the 2.4 square degree area of central parts of the SMC. For each object period, BVI photometry, astrometry, and R_21, φ_21 parameters of the Fourier decomposition of I-band light curve are provided. The Catalog is based on observations collected during the OGLE-II microlensing survey.

Tests of completeness performed in overlapping parts of adjacent fields indicate that completeness of the Catalog is very high: about 92%. Statistics and distributions of basic parameters of Cepheids are also presented.

Available is an interactive access to Cepheid database, allowing to select objects fulfilling user-given set of criteria and getting data of these objects.

All presented data, including individual BVI observations (about 4.7×105 BVI measurements) are available from the OGLE Internet archive. See README file there for details. Photometry of double-mode Cepheids in the SMC is available here, while photometry of single-mode second overtone Cepheids from this link.

Any comments about the data and the form of their presentation are welcome as they can improve the future releases of catalogs of variable stars detected by OGLE-II collaboration. Send your messages to this address.
