Query: Period-Luminosity Relations for Small Magellanic Cloud Cepheid Based on
  AKARI Archival Data   In this work we matched the AKARI archival data to the Optical Gravitational
Lensing Experiment-III (OGLE-III) catalog to derive the mid-infrared period
luminosity (PL) relations for Small Magellanic Cloud (SMC) Cepheids. Mismatched
AKARI sources were eliminated using random-phase colors obtained from the full
I-band light curves from OGLE-III. It was possible to derive PL relations in
the N3 and N4 bands only, although the S7, S11, L15, and L24 band data were
also tested. Random-phase correction was included when deriving the PL relation
in the N3 and N4 bands using the available time of observations from AKARI
data. The final adopted PL relations were: N3 = -3.370 logP + 16.527 and N4 =
-3.402 logP + 16.556. However, these PL relations may be biased due to the
small number of Cepheids in the sample.
