Summary
[edit]DescriptionIllustration of the speckle noise attenuation process achieved by ADI (geminiann07017c).tiff |
English: Illustration of the speckle noise attenuation process achieved by ADI. Panel (a) shows a typical image after subtraction of an azimuthally symmetric median intensity profile; panels (b) and (c) both show, with a different intensity scale, the same image after ADI subtraction; and panel (d) shows the combination of 117 such speckle-subtracted images. The faint point source visible in panel (d) at (2.43", 7.3º) is 1 million times fainter than the star. |
