Abstract:
We present here a nearly complete census of classical Cepheids in the
Magellanic System. The sample extends the set of Cepheids published in
the past by the Optical Gravitational Lensing Experiment (OGLE) to the
outer regions of the Large (LMC) and Small Magellanic Cloud (SMC). The
entire collection consists of 9535 Cepheids of which 4620 belong to
the LMC and 4915 are members of the SMC. We provide the I- and V-band
time-series photometry of the published Cepheids, their finding
charts, and basic observational parameters.
Based on this unique OGLE sample of Cepheids we present updated
period-luminosity relations for fundamental, first, and second mode of
pulsations in the I- and V-bands and for the WI extinction-free
Wesenheit index. We also show the distribution of classical Cepheids
in the Magellanic System.
The OGLE collection contains several classical Cepheids in the
Magellanic Bridge - the region of interaction between the Magellanic
Clouds. The discovery of classical Cepheids and their estimated ages
confirm the presence of young stellar population between these
galaxies.
Description:
The OGLE collection of classical Cepheids in theMagellanic Clouds
comprises 9535 objects (4620 in the LMC and 4915 in the SMC), of which
5168 pulsate solely in the fundamental mode (F), 3530 are single-mode
first-overtone pulsators (1O), 117 oscillate purely in the second
overtone (2O), 711 stars are double-mode Cepheids, and nine
triple-mode Cepheids.

Global notes:
Note (G1): Modes of pulsation as follows:
F = fundamental-mode
1O = first-overtone
2O = second-overtone
F/1O = double-mode F/1O
1O/2O = double-mode 1O/2O
1O/3O = double-mode 1O/3O
2O/3O = double-mode 2O/3O
F/1O/2O = triple-mode F/1O/2O
1O/2O/3O = triple-mode 1O/2O/3O
