 NOTE [1]: It is possible to turn off either the dynamic portion of the         
           Altimetry partials wrt to gravity coefficients or the geometric      
           portion but not both.                                                
                                                                                
 NOTE [2]: If geoid, earth tide, or ocean tide models are not supplied from     
           the Altimetry data, GEODYN IIE will automatically calculate the      
           models not supplied.                                                 

 NOTE [3]: For the geometric ocean tide model correction using the GOT99.2
           Ray tide model the analyst needs to include the following grid
           file in the directory where Geodyn IIE is executed:
  
           Hp:
           /geod4/geodyn/SUPPORT/dat_raytide/got99_grid.dat
           Cray:
           /u2/z8sgp/geodyn/support/dat_raytide/got99_grid.dat 


 NOTE [4]: To run this option the external grid file must be ftp'd from unitree 
           to the directory where Geodyn IIE is executed onto unit 29:

           Cray file:
           /u2/z8sgp/zms0l/mssdata/mssh95.one16th.deg.craybin.Z
           Hp file:
           /u2/z8sgp/zms0l/mssdata/mssh95.one16th.deg.hpbin.Z
