A Simplified Method to Determine the Coordinates of Albedo Features on Visible Disk of a Spherical Planet under Different Illumination Conditions

A simplified method for the determination of planetocentric coordinates of albedo features on visible disk of a spherical planet under different illumination conditions is offered. The method is precise and is intended for handling images of the planets obtained on ground-based and near-earth telesc...

V. A simplified method for the determination of planetocentric coordinates of albedo features on visible disk of a spherical planet under different illumination conditions is offered. The method is precise and is intended for handling images of the planets obtained on ground-based and near-earth telescopic observations. The position of a feature on the image of a planet is determined by means of rectangular coordinates in the transverse orthographic projection, independently of planetocentric declination of the Earth. To determine point positions on the illuminated part of the visible disk of a planet, we applied an auxiliary coordinate system connected with equator of intensity that allowed to exclude the influence of the planet’s phase and to make transition to the planetocentric coordinate system. The method is tested on images of Mercury and Mars. Предложен упрощенный метод определения планетоцентрических координат деталей альбедо на видимом диске сферической планеты при различных условиях ее освещенности. Метод является точным и предназначен для обработки изображений планет, полученных по наземным и околоземным телескопическим наблюдениям. Положение детали на изображении планеты определяется при помощи прямоугольных координат в поперечной ортографической проекции независимо от планетоцентрического склонения Земли. Для определения положения точек на освещенной части видимого диска планеты применена вспомогательная система координат, связанная с экватором интенсивности, что позволяет исключить влияние фазы планеты и осуществить переход к планетоцентрической системе координат. Метод проверен на изображениях Меркурия и Марса.
