    Hello from Japan!

I'm trying to do decay predictions of USA 193 debris by using SatEvo,
with following steps:

  1. Put two elsets of same object with different eporch in the same
     text file.

  2. Adjust SatEvo params so that results from two different elset
     are approx. same.

I've not yet done predictions of all known debris,
but here are some results:

  Common param: Solar flux flag: -F70
