There was a total of 31 tracking passes in August of 1997 with 4 of these being unattended tracking passes. There were 5 tracking passes that lost data due to problems with HALCA or the schedule file (SRT file). Of the 27 attended tracking passes 22 collected the maximum amount of valid data possible. Software problems resulted in the loss of data on 2 attended tracking passes while hardware problems resulted in the loss of data on 2 of the attended tracking passes. The operators were able to increase the amount of valid data collected in 4 of the 5 passes were data was lost due to hardware or software problems. Of the unattended tracking passes 3 of 4 obtained the maximum amount of valid data. The unattended tracking pass that lost data lost 100% of its data. If an operator had been present for this pass (9708101904) then most of the data could have been salvaged. Also, this unattended tracking pass delayed the detection of the hardware problem by one day which could have prevented the loss of 27% of the data on the next pass.
Of the 9 recording passes, 7 collected the maximum amount of good data while the other two recording passes lost 2% and 11% of the data during the pass.
22 of 27 attended passes had max good data.
Operators helped increase amount of good data in 4 of 5 ``bad'' attended passes.
3 of 4 unattended passes had max good data.
Operators would have increased amount of good data in 1 of 1 ``bad'' unattended passes.
A total of 0.29 tracking passes lost data due to software problems.
A total of 1.39 tracking passes lost data due to hardware problems.
A total of 1.37 tracking passes lost data due to problems with HALCA.
7 of 9 recording passes were completely successful.
A total of 0.13 recording passes lost data.
