Query: Distance determination to 12 Type II Supernovae using the Expanding
  Photosphere Method   We used early time photometry and spectroscopy of 12 Type II plateau
Supernovae (SNe IIP) to derive their distances using the Expanding Photosphere
Method (EPM). We performed this study using two sets of Type II supernovae (SNe
II) atmosphere models (E96, D05), three filter subsets (BV, BVI, VI) and two
methods for the host galaxy extinctions, which led to 12 Hubble diagrams. Using
the VI filter subset and the D05 models we obtained a dispersion in the Hubble
diagram of sigma = 0.32 mag and a Hubble constant of H0 = 52.4 +/- 4.3 km s-1
Mpc-1. We also applied the EPM analysis to the well-observed SN IIP SN 1999em.
With the VI filter subset and the D05 models we derived a distance of 13.9 +/-
1.4 Mpc, agreement with the Cepheid distance of 11.7 +/- 1.0 Mpc to the SN
1999em host galaxy (NGC 1637).
