There are cases when the NIRSpec WCS pipeline goes from "detector" to "msa" only. Since the wavelength units are converted from meters to micron at the end of the full pipeline, the output of a truncated pipeline is in meters. The last model in a truncated pipeline is a complex Slit2MSa model so it's not as straightforward to scale the output as with the full pipeline.
