  We study the vertical distribution of the highly inclined galaxies from the
Continuum Halos in Nearby Galaxies - an EVLA Survey (CHANG-ES). We explore the
feasibility of photometrically deriving the HI disk scale-heights from the
moment-0 images of the relatively edge-on galaxies with inclination >80 deg, by
quantifying the systematic broadening effects and thus deriving correction
equations for direct measurements. The corrected HI disk scale-heights of the
relatively edge-on galaxies from the CHANG-ES sample show trends consistent
with the quasi-equilibrium model of the vertical structure of gas disks. The
procedure provide a convenient way to derive the scale-heights and can easily
be applied to statistical samples in the future.
