butterfly is an interactive compiled Lisp function in `misc.el'.

Use butterflies to flip the desired bit on the drive platter.
Open hands and let the delicate wings flap once. The disturbance
ripples outward, changing the flow of the eddy currents in the
upper atmosphere. These cause momentary pockets of higher-pressure
air to form, which act as lenses that deflect incoming cosmic rays,
focusing them to strike the drive platter and flip the desired bit.

发帖数: 1474 | 26 叠加的主要好处是可以增加探测效率
首先要知道所谓detection, 指的是S/N大于某个阈值，比如说5sigma detection
指S/N>5. 现在假设你有单张image，有个源的信噪比是1，那你不能说是5sigma
detection.
但是如果你拍了很多张同样曝光时间的image并叠加的话，你的信噪比会提高，因为信
号总是在那儿的而随机error会降低，就好像重复试验降低统计误差一样。所以单张
image上不够5sigma detection的源，叠加的够多了就可能可以。
有时候还必须要把单张曝光时间拆成多次曝光，之后再叠加，这样做的目的就是像
chandra说的，方便扣cosmic ray, 避免背景饱和等等。有的时候还可以dither多次曝
光,
可以更好的扣天光背景（尤其是近红外），避免目标源落在CCD坏点上，或者更好的

是SQLite，就放在local hard disk上，你也可以自己写SQL statement。还有一部分叫
