  targets, and the observed nanodiamond 3.53~$\mu$m luminosity~$L_{3.5}$. The median value of each stelllar parameter in the total
  sample is given as a~reference. Values taken from \citet{houk,finkenzeller84,shore,vandenancker98,mora01,fuente01,habart03,ackesubmm,hamaguchi05}, AV04 and references therein.}\label{stelpar}
