| Abstract |
We present progress towards the creation of a new all-sky catalog of
intermediate velocity clouds using the Leiden/Argentina/Bonn (LAB)
Galactic HI survey. We have developed a Gaussian fitting program to fit
individual spectra. Each spectra is initially fit automatically with a
set of Gaussians, and then reviewed and adjusted, if necessary, by hand
by our undergraduate team. When a satisfactory fit is found, it is
submitted for review and adjustment by the senior team member.
Intermediate clouds and complexes are formed by grouping Gaussian
components by velocity and section of the sky. When complete, this will
be the first all-sky catalog of intermediate velocity clouds, which can
be compared to dynamical models of the Galactic fountain flows. We
present preliminary results for the catalog in the sky with Galactic
latitude greater than 45 degrees. This research was supported by NASA
ATP grant NNX10AI70G to the University of Wisconsin-Whitewater. |
