A5. SN 2002bo The host-galaxy absorption part of the R-correction to SN 2002bo
used the value R_V_ = 2.6 (intermediate between Galactic and SN 2001el values)
and a color excess E(B-V) = 0.44 mag derived from the AQUAA fit. This yields A_V
_ = 1.14, essentially the same value obtained by the optical photometry of
Krisciunas et al. (2004).
