"As a result, the new analysis finds asteroid diameter and other physical properties that have large differences from published NEOWISE results, with greatly increased error estimates. NEOWISE results have a claimed ±10% accuracy for diameter estimates, but this is unsupported by any calculations and undermined by irregularities in the NEOWISE results. Diameter estimates from bootstrap calculations appears to be no more than ±29.5% accurate when compared to diameters from radar, stellar occultations and spacecraft. NEOWISE errors for parameters like visible band albedo pv and near-IR albedo pIR1 and pIR2 are even higher, calling into question their utility."
