Nongravitational nominal solution

   Obs. arc:      1940 08 25 - 1941 04 01  
   Number of obs: 370   
   RMS:           1.49 arc second, (670 residuals used, 9.5% rejected residuals)  

Osculating, original and future orbits embargoed (were obtained in different project - results not published yet).


In the 17th edition of the Catalogue of Cometary orbits (2008):

Gravitational orbit (189 obs.) with 0 < 1/aori < 10-4 AU-1 - original barycentric orbit from Oort spike.

Note: in the following plots black denotes returning clones while red denotes escaping ones.The nominal solution is located at the center of the green circle. Each plot have a header where date of calculation and some other parameters are coded. Also numbers of returning (B=shown+omitted), escaping (C=shown+omitted) and all (T=shown+omitted) Vcs are shown.
