Loads a flat field frame. The software will display a file dialog so you can choose the file you want to load. A flat field calibration is automatically applied to all CCD Images that are loaded thereafter.
载入一个平场图片。该软件将显示一个对话框，你可以选择你想要载入的明场图片。此后载入的所有CCD图片将针对此平场图片做校正。
Note that a new Flat Field Frame should be taken for each observing session, to compensate for vignetting and image artifacts (for example, "dust doughnuts" caused by tiny dust particles in the optical path).
注意：每个新的平场图应该在每次观测期间拍摄，用以消除鬼影及其他人为因素（例如：由于光路中的微小尘埃导致的照片中的“黑圈”现象）
