威斯康星州H-Alpha Mapper(WHAM)是世界上最灵敏的仪器,用于观测银河系中的漫射光学发射线,以研究温暖的电离介质(Haffner等人,2003年)。已完成的WHAM巡天(WHAM-SS)是一个位置-位置-速度空间的全天空3D H-α发射图。该调查由超过50,000个光谱组成,每个光谱在不规则网格上均匀采样1度的天空光束。虽然有规则的网格数据立方体是可用的,但它们需要插值过程,有时会留下伪像。
The Wisconsin H-Alpha Mapper (WHAM) is the world’s most sensitive instrument observing diffuse optical emission lines in the Milky Way to study the warm ionized medium (Haffner et al., 2003). The completed WHAM Sky Survey (WHAM-SS) is an all sky 3D H-alpha emission map in position-position-velocity space. The survey is composed of over 50,000 spectra that each equally sample a 1-degree beam of the sky on an irregular grid. While regularly gridded data-cubes are available, they require an interpolation process that can sometimes leave artifacts.
