我们提出了一个国家的最先进的线性红移失真分析最近出版的IRAS点源目录红移巡天（PSCz）。该过程包括线性压缩成4096 Karhunen-Loeve（信噪比）模式，这些模式是从一个103 ×105的潜在模式库中挑选出来的，然后进行二次压缩成三个独立的功率谱，即星系-星系功率谱、星系-速度功率谱和速度-速度功率谱。最小二乘拟合的解相关功率谱产生一个线性红移失真参数
We present a state-of-the-art linear redshift distortion analysis of the recently published IRAS Point Source Catalog Redshift Survey (PSCz). The procedure involves linear compression into 4096 Karhunen–Loeve (signal-to-noise) modes culled from a potential pool of ∼3×105 modes, followed by quadratic compression into three separate power spectra, the galaxy–galaxy, galaxy–velocity and velocity–velocity power spectra. Least squares-fitting to the decorrelated power spectra yields a linear redshift distortion parameter
