Excellant Simone ! Appears to do an excellant job - many thanks! I spent the morning writing my own software to add line 0 with partial success-its not that trivial a task- at least for a novice programmer like me! I found that the database I had downloaded earlier contained about 16000 satellites,some with rather old epochs and it also contained some decayed satellites. Anyway your program now does all I need so many thanks and I can now go and do some other things that I was hoping to do before I got side tracked - like changing the optics on my setup.. Best wishes Greg _______________________________________________ Seesat-l mailing list http://mailman.satobs.org/mailman/listinfo/seesat-l
