was eliminated. From the list of errors received from the Presidence the following 
standard errors were obtained: 
M x = i 7.9 m, 
M Y = ^ 7.8 m, 
M p = V M* + Ml = ± 11.0 m. 
M H = ± 9.9 m. 
These standard errors include the points marked with IQ (see Section 2.4). 
Since the identification of these points is questionable it is indicated to eliminate these 
points. If this is done standard errors are obtained as shown in Table III:
