  The Wide-field Infrared Survey Explorer (WISE) observed 52 Centaurs and
Scattered Disk Objects in the thermal infrared, including the 15 discoveries
that were new. We present analyses of these observations to estimate sizes and
mean optical albedos. We find mean albedos of 0.08 +/- 0.04 for the entire data
set. Thermal fits yield average beaming parameters of 0.9 +/- 0.2 that are
similar for both SDO and Centaur sub-classes. Biased cumulative size
distributions yield size-frequency distribution power law indices ~ -1.7 +/-
0.3. The data also reveal a relation between albedo and color at the 3-sigma
level. No significant relation between diameter and albedos is found.
