Abstract:
We present the mid-infrared (mid-IR) period-luminosity relations
(PLRs) using over 1000 Mira variables in the Large Magellanic Cloud,
for the four Wide-field Infrared Survey Explorer and the four Spitzer
bands. These PLRs cover a mid-IR wavelength range from 3.4-22µm
and are presented separately for the oxygen-rich (O-rich) and
carbon-rich (C-rich) Miras. These relations can be used to measure
distances to individual O-rich and/or C-rich Mira stars with an
accuracy of 5% and 12%, respectively. They are the most accurate Mira
PLRs in the mid-IR to date.
Description:
Soszynski+ (2009, J/AcA/59/239) published two-band (I and V in the
Johnson-Cousins photometric system), 13yr long light curves covering
the time span 1996-2009. The full catalog can be found in online
databases through the OGLE webpage.
We supplemented publicly available Mira light curves with the
non-public OGLE-IV data collected over an additional 10yr since 2010.
We revised their pulsation periods using two-decade-long light curves.
The updated OGLE light curves have on average ∼1300 and ∼100 data
points in the I band and V band, respectively, obtained between
1996 December 29 and 2020 March 15.
See Section 2.2.
We crossmatched our catalog of Mira stars with two space-mission
databases containing mid-IR observations: WISE and Spitzer.
See Section 2.3.

Note (1): The full star ID is as in the original catalog
(Soszynski+ 2009, J/AcA/59/239). Table rows are sorted by star ID.
Note (2): The -9.999 value in the columns with the mean magnitudes means
that the star was not found in the mid-IR database, or the star was
rejected from the analysis due to reasons described in Section 2.
