Notes: ^a Computed by assuming the following $A_{\rm V}$ values: 10 mag for #25 and 37 jets, 18 mag for #57 jet (L02). For the main jet we adopted, for each knot, the extinction value derived by the low-resolution spectroscopy.
^b Derived by assuming blackbody extrapolation longward the last photometric point (that in N band).
^c Revised with respect to the value given by M99.
