Observed SFD of the Veritas family (grey, solid). Its extrapolation (dotted) is supported by the observed 9.3° IRAS dust band (Nesvorný et al. 2006), at approximately 30 µm (error bar). Moreover, the initial SFD (Pantone 7633C, dashed) is supported by the excess of extraterrestrial He-3 (Farley et al. 2006), which 8.3 Myr ago ‘overshot’ the background level by a factor of ~3. The interpolation to metre sizes (error bar) implies the abundance of CM chondrite meteoroids.
