Notes. We find very good agreement with the total NGC 4151 fluxes as listed in the ALLWISE catalog (Col. 5). Our total fluxes are systematically slightly lower than the catalog fluxes, which is partly caused by the correction term that we applied to shift our fluxes from the mean epoch to 2010 May (see text for details). From 2010 MayDecember, the AGN got approximately 25% brighter.
