obs_description      = The VTSS is a wide-field image survey of the Galaxy's warm ionized interstellar medium (WIM, a 10,000 K plasma). The instrumentation used is the Virginia Tech Spectral Line Imaging Camera (SLIC), specially designed for obtaining sensitive, arcminute-resolution, 10-degree wide images of the 6563 angstrom H-alpha recombination line of hydrogen, and the [SII]6717,6731 angstrom doublet emission of singly ionized sulfur. This survey cover the northern hemisphere (declinations greater than -15 degrees).
