Leonids 1999
Visual results in Japan (The Nippon Meteor Society).

ZHR has been computed with:
-  gamma = 1.0 (correction of Radiant elevation)
-  r = 2.0   (equal "IMO Shower Circular,LEONID Activity 1999")
-  excluding:observations under unfavourable condition
   (T<30m, Lm<4.0mag, Cl>0.4, RP-h<10deg)
-  SD   : standerd deviation of ZHR
-  Err. : ZHR * 1/SQRT(#Leo)
