Megastar V5 Willmann Bell


Recommended Posts

Has anyone updated the Asteroid data for Megastar v5? If you read the following instruction it looks simple but I cannot figure out how to unzip the file  astorb.dat.gz Please see the instruction here:-


I have gzip.exe to unzip but it just will not do anything i.e. unzip the file. Does anyone have a copy of the updated file  asteroid.lwl  that will bring all the asteroid orbits and ephemeris upto date? I would really appreciate a copy. I have tried emailing Willmann Bell directly but they never answer.

Hi Julian,  It worked - fantastic!  with thanks to you. Asteroid data now agrees with the MPC ephemeris. 

Many thanks and clear skies.


PS. I have also updated the comet data on Megastar v5 but now get a message saying 'unable to compute coordinates - no convergence' this comes up twice before Megastar will load. I am assuming that two comets in the MPC data either have bad data entries or have incomplete data. Has anyone else had this problem?
