Dear List,
A retraction to my comment yesterday about the lack of concordance
between Mike McCant's ALLDAT and GEO elset files. I went back and checked
my quick and dirty little program (following a note from Mike) and note
that I have a filter for the ALLDAT file to drop any elset with an epoch
greater less than five days from today. In contrast, for the GEO file, I
did not have the same filter on purpose since orbits for geosats are
"stable". As a result, the exception records I thought I identified were
really the elsets I purposely dropped from the ALLDAT file (due to aging)
but then immediately picked up in the GEO file. I should have realized this
was happening since the exceptions were, for the most part, one to two
weeks old (as noted in the earlier message) ... no kidding!
Never code or hack during all-nighters ... it can lead to illusions
and lapses in proper thought .... :-)
My sincere apologies to Mike.
Anthony.
