The "Strange Days" of Phobos-2: in Mars' orbit (4)

Each image includes channels 1 to 3 and a corresponding IKI processed image. Additional work was needed to correct spurious data in Channel 1 (causing the jagged misalignment of some scanlines). This may not be possible using NASA's copy of the data, which has parity bits removed. IKI performed additional processing in the frequency domain to remove periodic noise and replace bad pixels and scanlines with local median values.

White pixels appearing in columns 228-231 of the channel-3 CCD are caused by a fault in the electronics, but gained notoriety when misidentified by UFO experts as an Alien Spacecraft.
