c     s1,s2,s5, azimuth, elevation angles
c     edot, in degrees/second
c     output selection
c     18ocdt01 added galileo frequencies
c     added option 66, which is all data < 30 degrees
c     20mar02 added msec to the output, sent from main code

c     asked for all, but < 30 degrees elevation
c     i made 98 and 99 do the same thing so i would 
c     not interfere with my existing file structures at CU
