There was a total of 26 tracking passes in December of 1997 with 6 of these being unattended tracking passes. Of the 20 attended tracking passes 14 collected the maximum amount of valid data possible. Software problems resulted in the loss of data on 1 attended tracking passes while hardware problems resulted in the loss of data on 4 of the attended tracking passes. The operators were able to increase the amount of valid data collected in 3 of the 6 passes were data was lost due to hardware or software problems. Of the unattended tracking passes 3 of 6 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 3 of 3 passes.
Of the 14 recording passes, 8 collected the maximum amount of good data while the other recording passes lost 21%, 100%, 100%, 67% and 3% of the data during the pass. Two of the recording passes lost data due to inclement weather.
14 of 20 attended passes had max good data.
Operators helped increase amount of good data in 3 of 6 ``bad'' attended passes.
3 of 6 unattended passes had max good data.
