  With thermal infrared observations detected by the NEOWISE project, we have
measured diameters for 1742 minor planets that were also observed by the
Infrared Astronomical Satellite (IRAS). We have compared the diameters and
albedo derived by applying a spherical thermal model to the objects detected by
NEOWISE and find that they are in generally good agreement with the IRAS
values. We have shown that diameters computed from NEOWISE data are often less
systematically biased than those found with IRAS. This demonstrates that the
NEOWISE dataset can provide accurate physical parameters for the >157,000 minor
planets that were detected by NEOWISE.
