The distribution of the intensity of the catherine lansfield ombre rainbow clouds eyelet curtains comet Ison C/2013 is studied by taking its histogram.This distribution reveals four distinct regions that related to the background, tail, coma and nucleus.One dimensional temperature distribution fitting is achieved by using two mathematical equations that related to the coordinate of the center of the comet.The quiver plot read more of the gradient of the comet shows very clearly that arrows headed towards the maximum intensity of the comet.
