  Parameters and abundances have been derived for 435 Cepheids based on an
analysis of 1127 spectra. Results from five or more phases are available for 52
of the program stars. The latter set of stars span periods between 1.5 and 68
days. The parameters and abundances show excellent consistency across phase.
For iron, the average range in the determined abundance is 0.11 from these 52
stars. For 163 stars with more than one phase available the average range is
0.07. The variation in effective temperature tracks well with phase, as does
the total broadening velocity. The gravity and microturbulent velocity follow
phase, but with less variation and regularity.
  Abundance gradients have been derived using GAIA DR2 parallax data (GAIA
Collaboration et al. 2016, 2018), as well as Bayesian distance estimates based
upon GAIA DR2 from Bailer-Jones et al. (2018). The abundance gradient derived
for iron is d[Fe/H]/dR = -0.05 dex/kpc, similar to gradients derived in
previous studies.
