%X Observed spiral galaxy rotation curves allow a measurement of the warm dark matter particle velocity dispersion and mass. The measured thermal relic mass <em>m</em><sub><em>h </em></sub><span style=\"white-space:nowrap;\"><span style=\"white-space:nowrap;\">&amp;asymp;</span> </span>100 eV is in disagreement with limits, typically in the range 1 to 4 keV. We review the measurements, update the no freeze-in and no freeze-out scenario of warm dark matter, and try to identify the cause of the discrepancies between measurements and limits.
