Abstract:
JHKs magnitudes corrected to mean intensity are estimated for Large
Magellanic Cloud (LMC) type II Cepheids in the OGLE-III survey the
third phase of the Optical Gravitational Lensing Experiment (OGLE).
Period-luminosity (PL) relations are derived in JHKs as well as in a
reddening-free VI parameter. Within the uncertainties, the BL Her
stars (P<4d) and the W Vir stars (P=4 to 20d) are colinear in
these PL relations. The slopes of the infrared relations agree with
those found previously for type II Cepheids in globular clusters
within the uncertainties.
Description:
S08 (Soszynski et al., Cat. J/AcA/58/293) catalogued 197 CephII
variables in the LMC. We searched for near-infrared counterparts in
the IRSF catalogue (Kato et al., 2007PASJ...59..615K 2007PASJ...59..615K, Cat. II/288).

Note (1): Nine S08 sources are absent because their IRSF counterparts were not
found, and 15 S08 sources are listed twice because they are identified with
two counterparts from neighbouring fields of the IRSF survey.
