Notes.

^(a)

All JHK_S photometry is from 2MASS. Mid-infrared photometry is from the ALLWISE catalogue.

^(b)

S9 is not an emission-line star, but it is immersed in the bright nebulosity of IRAS 06422+0023. Its mid-infrared colours are thus dominated by nebular emission, and serve as a comparison.

^(c)

This value is not reliable, as its associated error is ±0.52.
