资源简介：
Values are shown derived from fits to the linespread and to the MTF, and for grayscales of 128 and 255. The scale is the frequency in cycles/deg at which the Gaussian declines to e−π = 0.0432.
本次给出的数值源自对线扩展函数（linespread）与调制传递函数（Modulation Transfer Function, MTF）的拟合，且对应灰度级为128与255。该标尺对应的是高斯分布衰减至e^(-π)≈0.0432时的空间频率，单位为周/度（cycles/deg）。
