Abstract
Recently, we have discovered an error in our Monte-Carlo
spectral fitting routine, more specifically where the errors on the
fluxes were rescaled to get a reduced χ2 of 1. The rescaled errors
were too big, resulting in too wide a range of “good” fits in our
100 step Monte-Carlo routine.
This problem affects Figs. 7−9 and TablesA.1, A.2 in Gielen
et al. (2008), Table 3 in Gielen et al. (2009a), and Table 4 in
Gielen et al. (2009b).
We corrected for this error and present the new values and
errors in the tables below. The new values and errors nearly all
fall within the old error range. Our best χ2 values and overall
former scientific results are not affected. With these new errors
some possible new trends in the dust parameters might be
observed. These will be discussed in an upcoming paper where
we extend the sample presented in Gielen et al. (2008) with
newly obtained SPITZER-IRS data.
