- Barger et al. (2003) list the photometry
in the HK' filter. We converted this photometry into K band by using
the relation
HK'-K = 0.13+0.05(I-K), provided in the same paper.

- ... type
- The intrinsic shape of the standard
stars was corrected by using
the spectral libraries of Pickles (1998) or through the
method discussed in Maiolino et al. (1996) in the case of late type main sequence
stars.

- ...(Perola et al. 2004)
- The extinction expected from
the X-ray absorbing column density assuming a Galactic gas-to-dust ratio
and extinction curve is higher (
(exp)
10 mag) than inferred
from the near-IR spectrum, but marginally consistent given
the errors on
.
Moreover, a mismatch between optical and
X-ray absorption is common to most AGNs (Maiolino et al. 2001b).
