The mosaic includes image data taken through a narrowfilter that transmits only the red light of hydrogen atoms.
这张拼贴图中所含的图片数据是通过窄带滤波器得到的,它只会传播氢原子发出的红光。

The estimator utilizes constraints on both the subspace and the errors of steering vectors to design a narrowfilter. The filter outputs the spectral estimate with the filtering vector as its input.
