Author comment for 1984omch.book.....L
There exists an A&A article of 1986 with the same name from the same author, however with different results. For example, in the A&A article is another, shorter backward integration of the comet for test babilonean observations of the comet, whose interpretation however the author stated as doubtful; the better backwards integration (sometimes citated) is here in this publication.
