Starting with uploads of two processed images to astromomy.net (and this image) following a hint of Emily's very useful TPS blog post, I've obtained the coordinates of the star background.
CODE Center (RA, Dec): (270.678, -14.637) Center (RA, hms): 18h 02m 42.813s Center (Dec, dms): -14° 38' 12.604" Size: 34.9 x 34.9 arcmin Radius: 0.411 deg Pixel scale: 1.02 arcsec/pixel Orientation: Up is -159 degrees E of N Then I've the assembled a blink gif between a map obtained from Google Sky as a reference, and a roughly brightness adjusted version of the filtered and merged OpNav Campaign 3, LORRI 4x4, images (until 2015-05-01): Besides the bright Pluto/Charon barycenter, I found two subtle, but significant differences: 1 - could be a glitch in the reference map, or a variable object, 2 - unclear, could be a variable star, or a TNO / moon; I can rule out a processing artifact almost with certainty, as well as an incompletely filtered CR hit, since the feature is present in several LORRI images. |
