Abstract (from CDS):

We have completed a robotic wide-angle imaging survey of the southern sky (δ=+15° to -90°) at 656.3 nm wavelength, the Hα emission line of hydrogen. Each image of the resulting Southern Hα Sky Survey Atlas (SHASSA) covers an area of the sky 13° square at an angular resolution of approximately 0'.8 and reaches a sensitivity level of 2 R (1.2x10–17 ergs cm–2.s–1.arcsec–2) pixel–1, corresponding to an emission measure of 4 cm–6.pc and to a brightness temperature for microwave free-free emission of 12 µK at 30 GHz. Smoothing over several pixels allows features as faint as 0.5 R to be detected.
