Unfortunately, the PSK-1 has been out of commission for nearly 
one year. A number of dalays of several months each in 
scheduling the repair have forced the authors to cancel the 
planned comparison with comparator observed bundle adjustment 
results of the Milton-Rrooklyn block. 
RESULTS 
In Table 1 the results of the first test series are summarized, 
dealing with the different sets of additional parameters. 
The test series using the Fdmundston Block is summarized in 
Table 2, while the Milton-Brooklyn Block test results are 
listed in Table 3. Since comparator measurements were not 
available for the Milton-Brooklyn Block, and since the control 
vas located such that effectively none could be used as check 
points, mean coordinates were computed for all points using all 
adjustments. RMS values against these were used for comparison 
purposes in addition to the internal RMS values in the model - 
photo systems respectively.
