Changes for version 0.083 - 2017-09-13

  • Add -decayed to eg/visual.
  • This eliminates decayed bodies. I decided not to remove these from the magnitude table because of historical interest.
  • Kelso removes 38253 from visual.txt. Decayed 2017-08-18.
  • Kelso marks 25471 Iridium 77 failed
  • Kelso marks 24949 Iridium 30 failed
  • Kelso adds 33411 to visual.txt.
  • Kelso adds 11251 METEOR 1-29 to visual.txt
  • Use qsmag instead of mcnames to suppliment magnitudes in the canned magnitude table. As of July 24 2017 mcnames appeared to be double-compressed and corrupt besides. Both are maintained by Mike McCants, but the former is input to his QuickSat program and so likely to be less fragile. I hope. The mcnames file was eventually corrected, but I am sticking with qsmag for now.
  • Kelso reports decay of Iridium 74.
