Welcome to the LAB Survey server of the Argelander-Institut für Astronomie in Bonn!This server was set up for the EU grant is 510308-LLP-1-2010-1-FR-COMENIUS-CMP. The complementary EU-HOU-Observer page is here: http://euhou.obspm.fr
An explanation how spiral structure of the Milky Way can be derived from this web interface is given here: HI_Spirals_HowTo
If you like to determine spiral arms in the Milky Way you can download templates for plotting.
Plain millimeter paper is available here: Galactic grid
Further information is also available at the SALSA homepage

Below you will find videos showing a sweep in velocity through the data cube of the LAB survey, in Galactic center and anticenter projection.
This video shows a sweep in latitude through a data cube that has been regridded to demonstrate differential Galactic rotation. Longitude is horizontally, velocities are displayed vertically.
