RESULTS FROM HI IMAGE SCRUBBING

Section 5.3.6 of the Software Operations Manual briefly describes two capabilities of the SECCHI flight software to remove cosmic rays from HI images. The first is a two image scrub where the current image is compared with the previous image on a pixel by pixel basis. If the current image pixel is greater than previous pixel plus N times the photon noise of the pixel, the pixel is replaced with the previous pixel. The three image scrub takes the median value of the current, previous and oldest image.
