Left panels: fit of the o-NH2D lines at 86 GHz (upper panel) and 333 GHz (lower panel) with the hyperfine structure caused by the D nucleus. Right panels: fit of the p-NH2D lines at 110 GHz (upper panel) and 333 GHz (lower panel). Note that fits of similar quality are obtained if the hyperfine structure caused by D is omitted.
