 Standard magnitudes for Zenit second stages
 ---------------------------------------------

 From Russell's observations (1980 Jan 01 to 1995 Nov 30) I have derived
 standard magnitudes (1000 km, 90 deg) for the Zenit second stages.

 There are 387 observations marked with "S" (steady) and 35 observations
 marked with "R" (regular variations).
