There was a total of 26 tracking passes in January of 1998 with 12 of these being unattended tracking passes. Of the 14 attended tracking passes 6 collected the maximum amount of valid data possible. Software problems resulted in the loss of data on 0 attended tracking passes while hardware problems resulted in the loss of data on 8 of the attended tracking passes. The operators were able to increase the amount of valid data collected in 1 of the 8 passes were data was lost due to hardware or software problems. Of the unattended tracking passes 3 of 12 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 4 of 9 passes. Two unattended tracking passes (9801041728 and 9801061109) delayed the detection of a hardware problem by 2 days by not having an operator present or a call-out task. This resulted in an extra 1-2 tracking passes being lost.

Of the 10 recording passes, 1 collected the maximum amount of good data while the other recording passes lost 100%, 15%, 100% , 100% , 100% , 100% , 100% and 1% of the data during the pass.



$\bullet$ 6 of 14 attended passes had max good data.

$\bullet$ Operators helped increase amount of good data in 1 of 8 ``bad'' attended passes.

$\bullet$ 3 of 12 unattended passes had max good data.

$\bullet$ Operators would have increased amount of good data in 4 of 9 ``bad'' unattended passes.

$\bullet$ A total of 0.00 tracking passes lost data due to software problems.

$\bullet$ A total of 12.01 tracking passes lost data due to hardware problems.

$\bullet$ Inclement weather resulted in the loss of 0.50 tracking passes.

$\bullet$ 1 of 10 recording passes were completely successful.

$\bullet$ A total of 6.16 recording passes lost data.
