NOTE [1]: If the start and end dates are left blank electronic biases

NOTE [2]: The station number, satellite ID and bias type are required.          
          Blanks and /or zeroes will not work.                                  
                                                                                
NOTE [3]: If the measurement type is larger than 99 (3 digit) use               
          EBIASM card to specify it.

EBIAS (cont)

                                                                                
                                                                                
                           GEODYN-II E-BIAS TYPES                               
                                                                                
        The GEODYN-II E-bias types include all of the GEODYN-II measurement     
types as well as other types which are an extension of the simple measurement   
bias.                                                                           
                                                                                
        At present, the only E-bias types defined include simple constant       
measurement biases. Other future E-bias types will include linearly varying     
measurement biases and observation scale biases.                                
                                                                                
        E-bias type numbers are assigned as follows:
