Точность любительских позиционных ПЗС наблюдений

[Timur]

Публикую здесь письма с обработкой моих ПЗС наблюдений астероидов, в первую очередь потенциально опасных для Земли. Обработка проводилась в Пулковской обсерватории О. П. Быковым. Что можно сказать, при фотографических наблюдениях такие точности и не сгились, и это достигнуто при плохом качестве часового ведения, так что не является пределом для 25-см 1:4.8 телескопа.

Тимур, поздравляю. Все ОК. Смотри сам. Остальное - потом. О.П.

Тимур, срочно высылаю то, что удалось сосчитать.
Для остальных объектов у меня в каталоге нет орбит. В целом, все
очень хорошо. Так держать.
