only use these experiments to estimate EOP. I never use this
   option anymore. Default is NO.
 
6. Sig1 uncertainty (99 no constraints, 5 is nominal): This is the size
   of the largest component of the EOP. If the EOP error is larger than
   this, then the measurement is not used. Default is 5.0
 
7. Rescale formal errors by how much? It is known that the formal error
   solves reports are two small. This option allows you to inflate them
   (or for that matter, deflate them.) If you type "Yes" to the def
