Comet C/1913 Y1 Delavan

Nongravitational nominal solution

  Obs. arc:      1913 10 25 - 1915 09 07 
  Number of obs: 1009  
  RMS:           2.00 arc second, (1860 residuals used, 7.8% 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 (339 obs.) with 0 < 1/aori < 10-4 AU-1 - original barycentric orbit from the 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.
