COMPUTERIZED COMPUTATION OF GENERAL PERTURBATIONS FOR THE ASTEROIDS OF FLORA GROUP I. APPLICATION OF HANSEN METHOD

He Miao-fu Zhang Jie(Shanghai Observatory, Academia Sinica)  
The general perturbations of the asteroids of Flora group (975″n1150″, n~the mean daily motion) due to Jupiter have been automatically computed on IBM 4341 Computer with Hansen method by manipulating Broucke's Symbolic Poisson Series Processor. The results have been compared to that computed with Bohlin group method before. The obtained conclusions are as follows: 1. Instead of Bohlin group method, the program for Hansen method coded on IBM4341 Computer is available to compute the general perturbations of the asteroids with much accuracy and efficiency. 2. In 1000″n1100″ case, when both eccentricity (e) and inclinat tion (i) of the asteroidal orbit are moderate, Strmberg table is suitable to be applied to compute the perturbative coefficients. Its maximum error would be less than 20′. 3. In n~1047″ case, n′/n~2/7 (n′-the mean daily motion of Jupiter), that is close to the commensurability, the long periodic term (2—7) should be taken into account. But the formula of de la Villemarque used to compute the coefficients of this term is less precise. 4. In 975′n1000′ case, Strmberg table is unsuitable to use, especially, when both e,i are larger. Therefore, de la Villemarque's view is incorrect. 5. In n~997′ case, n′/n~3/10, that is close to another commensurability, the long periodic term (3—10) should be taken into account.
