Intensity maps of comet C/2011 KP36 (Spacewatch) in the g-sdss and r-sdss filters. (a) Direct images of the comet with the isophots differing by a factor ; (b) image processed by a rotational gradient method (Larson & Sekanina 1984); (c), (d), and (e) images to which a division by 1/ρ profile, azimuthal average, and renormalization methods were applied, respectively (Samarasinha & Larson 2014). The color scale does not reflect the absolute brightness of the comet; it is only used to distinguish the areas of intensities that differ by . Jet-like structures in the coma are indicated by J1, J2, J3, and J4. The arrows point in the directions to the Sun (⊙), north (N), east (E), and the negative velocity vector of the comet as seen in the observer’s plane of sky (V). Negative distance is in the solar direction, and positive distance is in the antisolar direction.
