Intensity maps of comet C/2014 N3 in the g-sdss and r-sdss filters. Panels a and b: direct images of the comet. Panels c and d: images processed by the rotational gradient method (Larson & Sekanina 1984). Panels e and f: images to which a division by the 1/ρ profile has been applied (Samarasinha & Larson 2014). The color scale does not reflect the absolute brightness of the comet. Arrows in panels e and f indicate the contaminating field stars. The arrows point toward the Sun, the north, the east, and the negative velocity vector of the comet as seen on the plane of the sky.
