Abstract Reanalysis of the NIR spectrum of the star-formation object WL 16 indicates that the observed infrared CO emission has a high optical depth, creating a CO emission continuum feature. A new extinction value A(v) = 40 places the Brackett gamma emission within the normal range for low-luminosity line excess sources. The observations are consistent with a spherical cooling outflow with the infrared CO and hydrogen emission arising from physically separate regions. Other geometries are not excluded by the observations.
