  \caption{Summary of the  IR fluxes measurements for  all types of isolated NSs with an identified IR~counterpart i.e.  rotation-powered pulsars (rows~1$-$5)  and magnetars  (rows~6$-$11).   The  columns give  the observed  $J,  H,  K,   K_{\rm s}$~magnitudes  (an  hyphen  stands  for
non-detection,  values  in italics  have  been extrapolated),  the
distance,  and the  interstellar extinction~$A_V$  either derived
from existing  optical measurements~(O) or from  the $N_{\rm H}$ derived
from the  fits to the X-ray  spectra~(X) by using  the relation of
Predehl \&  Schmitt (\cite{pred95}). $K$-band  flux values in  italics have
been  derived  from the  extrapolation  of  the  $J$ and  $H$-band fluxes. }\label{IRsummary}
