Notes.

(a)

Saturated in MIPS data.

(b)

 Significant uncertainty in the MSX flux densities on account of the extended structure seen in the higher resolution MIPS data.

(c)

An offset of 2.8'' between the GLIMPSE and MIPSGAL point sources casts some doubt about the association of the two sources.
