3.11.3 Sigma Code - mandatory if 'Use Phase Obs' is set
+When 'Use phase obs' is set in BNC the PPP solution will be carried out using both code and phase observations. A sigma of 5.0 m for code observations and a sigma of 0.02 m for phase observations (defauls) is used to combine both types of observations. +As the convergence characteristic of a PPP solution can be influenced by the relation between the sigmas for code and phase observations, you may like to introduce you own sigma for code observations which differs from the default of 5.0 m. +
+Note that only values between 0.3 m and 50.0 m are accepted as code sigma. +
