The Distribution of the Elements in the Galactic Disk II. Azimuthal and
  Radial Variation in Abundances from Cepheids
  This paper reports on the spectroscopic investigation of 101 Cepheids in the
Carina region. These Cepheids extend previous samples by about 35% in number
and increase the amount of the galactic disk coverage especially in the
direction of l \approx 270{\deg}. The new Cepheids do not add much information
to the radial gradient, but provide a substantial increase in azimuthal
coverage. We find no azimuthal dependence in abundance over an 80{\deg} angle
from the galactic center in an annulus of 1 kpc depth centered on the Sun. A
simple linear fit to the Cepheid data yields a gradient d[Fe/H]/dRG = -0.055
\pm 0.003 dex/kpc which is somewhat shallower than found from our previous,
smaller Cepheid sample.
