There was a total of 28 tracking passes in October of 1997 with 5 of these being unattended tracking passes. Of the 23 attended tracking passes 11 collected the maximum amount of valid data possible. Software problems resulted in the loss of data on 3 attended tracking passes while hardware problems resulted in the loss of data on 10 of the attended tracking passes. The operators were able to increase the amount of valid data collected in 7 of the 11 passes were data was lost due to hardware or software problems. Of the unattended tracking passes 0 of 5 obtained the maximum amount of valid data. The presence of an operator at the ``bad'' unattended tracking passes would have increased the amount of good data in 5 of 5 passes.
Of the 7 recording passes, 2 collected the maximum amount of good data while the other recording passes lost 3%, 1%, 100%, 100% and 20% of the data during the pass.
11 of 23 attended passes had max good data.
Operators helped increase amount of good data in 7 of 12 ``bad'' attended passes.
0 of 5 unattended passes had max good data.
Operators would have increased amount of good data in 4 of 5 ``bad'' unattended passes.
A total of 0.35 tracking passes lost data due to software problems.
A total of 3.88 tracking passes lost data due to hardware problems.
2 of 7 recording passes were completely successful.
