| Abstract |
We describe a new effort to use the Leiden/Argentina/Bonn (LAB) Galactic
HI survey to update the high-velocity clouds catalog of Wakker and van
Woerden (1991). The LAB survey (Kalberla et al 2005) combined the
Leiden-Dwingeloo survey (Hartmann and Burton 1997) with a complementary
southern sky survey (Arnal et al 2000). This survey provides improved
angular spacing (0.5 deg vs. 1 deg) and velocity resolution (1 km/s vs.
16 km/s), although it was less sensitive than previous surveys. We
describe how we fit the LAB high velocity gas with Gaussian components,
providing three levels of review for the quality of fits, and compare
the resulting high velocity cloud catalog to previous results for
galactic latitudes greater than b=45 degrees. This research was
supported by NASA ATP grant NNX10AI70G to the University of
Wisconsin-Whitewater. |
