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:柱狀圖縮放,濾鏡處理或去卷積)在天文測量或光度測量軟件中將不被推薦,因為這樣的操作會對目標(biāo)星的光流量和聚焦中心產(chǎn)生誤差。
