| The Wisconsin H-alpha Mapper has surveyed the distribution and kinematics of ionized gas in the Northern sky in 1997-1998 and then in the Southern sky in 2009, at an angular resolution of 1°. The combination of the two survey represents the first all-sky survey of the diffuse H-alpha emission (6563 Angstroms) from the Milky-Way and consists of more than 49000 spectra (-100 Km/s < vLSR<+100 Km/s). | The Wisconsin H-alpha Mapper has surveyed the distribution and kinematics of ionized gas in the Northern sky in 1997-1998 and then in the Southern sky in 2009, at an angular resolution of 1°.
