Miranda ephemeris gone haywire after 1/1/2011?


 

Hi all

I'm running RC-11 under Cygwin and have found that starting 1/1/2011 the ephemeris for Uranus' satellite Miranda is completely out of whack. You can actually see it disappear if you run the time through 00.00UT. I checked with the calculator on the S&T website and the other satellites seem OK.

I've checked the usual Cygwin related issues like EOL type etc, but to no avail. After 1/1/2011 the second set of data files are used (Uranus.1020), and I'm wondering whether there is an error in the BDL data for Miranda.

Can anyone else confirm that they are seeing the same issue?

thanks very much
Piero

Hello Piero, thanks for the report. I have confirmed your report on a fresh compile of RC11 on Ubuntu 10.10. I will look into it and update the forum if I learn anything.

RC13 now includes a fix for this issue. Basically the file uranus.1020 was corrupted.
