histogram scaling meaning in English

直方图定标

Further image processing ( e . g . , histogram scaling , application of filters or deconvolution ) is not recommended for astrometric or photometric applications , because it will distort the centroids and flux of the objects in the image
其他的操作（如：柱状图缩放，滤镜处理或去卷积）在天文测量或光度测量软件中将不被推荐，因为这样的操作会对目标星的光流量和聚焦中心产生误差。
