Abstract:
We present a catalog of 99 candidate clusters and groups of galaxies
in the redshift range 0.1<zphot<1.3 discovered in the Spitzer
First-Look Survey (FLS). The clusters are selected by their Rc-3.6um
galaxy color-magnitude relation using the cluster red-sequence
algorithm. Using this cluster sample, we compute the 3.6, 4.5, 5.8,
and 8.0um, cluster luminosity functions (LFs).
Description:
The IRAC imaging data for this project were observed as part of the
publicly available, Spitzer FLS. The extragalactic and Galactic
components of the Spitzer First Look Survey were executed on the
observatory December 1-11, 2003 and the ecliptic component was
executed January 21-22, 2004.

--------------------------------------------------------------------------------
Note (1): Bgc is the correlation amplitude between the cluster center and
galaxies; the centroid that produces the largest value should be the
best centroid of the galaxy population. See section 3.8 and 3.9 for
further details (exoressed in Mpc1.8)
Note (2): Using Muzzin et al. (2007ApJ...663..150M 2007ApJ...663..150M):
logM200=(1.62±0.24)logBgc+(9.86±0.77) and
logR200=(0.53±0.09)logBgc-(1.42±0.29).
See section 4 for further details.
