The optical depth of the silicate band τsilicate towards star #2 (dashed line) and #947 (full line) as determined from Spitzer-IRS and ISOCAM-CVF observations, respectively. Although the S/N of the observations does not allows for an interpretation of the details, we note that for star #947 the band peaks at  ≈ 0.109 μm-1 corresponding to 9.2 μm.
