Kelly,

I have corrected several values in your table, the corrected version
is attached.  Let me know if there is anything unclear.  
A few comments:

- Discovery date of satellite:  I consistently put there a time when the 
observations have been made.  In the case of 1994 AW1, the actual discovery
of the satellite was made in 1995 (it was a part of my PhD thesis).

- You had there a wrong value for the orbital period of the satellite of 
45 Eugenia.  I don't know an up-to-date value, so I recommend to check
with Bill Merline.

- The suspicion that 1999 KW4 is binary is based on poor data and I wouldn't
normally mention it until we have more data to support the suspicion.
But I understand that it comes to a favorable apparition in next month and
therefore it is interesting to mention it as well.  I recommend, however, 
you to mention in your article that the data are poor so the suspicion is not 
so strong as in other cases.

- We have two more suspected binary NEAs, but since we haven't published 
the results yet, I think that it is not necessary to mention them
in your article particularly.

Let me know if you need any further information from me.

Cheers,

Petr Pravec
