IRS spectrum and photometric data of 04016+2610 and an envelope model fit with ﹩L=4.5﹩ L_⊙, ﹩\rho _{1}=4.5\times 10^{-14}﹩ g cm⁻³, ﹩R_{c}=100﹩ AU, ﹩\eta =1.0﹩, ﹩\eta _{\mathrm{star}\,}=0.1﹩, ﹩\theta =5^{\circ }﹩, ﹩i=40^{\circ }﹩, an inner disk radius of 1 stellar radius, and an outer envelope radius of 6000 AU. The CO₂ ice abundance was set to ﹩1.5\times 10^{-4}﹩. The gray lines represent the different model components: the envelope (long‐dashed line), the star (dotted line) and the disk (dash‐dotted line), both extinguished by the envelope, and the sum of all components (solid gray line).
