There was a total of 43 tracking passes in August of 1999 with 3 of these being an unattended tracking pass. Of the 40 attended tracking passes 32 collected the maximum amount of valid data possible. Of the 3 unattended tracking passes 2 collected the maximum amount of good data. The vertex overheating due to the Peltier heater/cooler failing or being insufficient along with unseating an IC connector in the demodulator resulted in the loss of data for 6 tracking passes. 24 tracking passes lost data due to the link from HALCA not showing up on time. 2 tracking passes lost data due to twenty or thirty second dropouts of the HALCA signal.
Of the 15 recording passes, 13 collected the maximum amount of good data.
32 of 40 attended passes had max good data.
Operators helped increase amount of good data in 2 of 8 ``bad'' attended passes.
2 of 3 unattended passes had max good data.
Operators would have increased amount of good data in 0 of 1 ``bad'' unattended passes.
A total of 0.15 tracking passes lost data due to software problems.
A total of 0.81 tracking passes lost data due to hardware problems.
13 of 15 recording passes were completely successful.
15 of 15 recording passes were at least 80% successful.
A total of 0.19 recording passes lost data.
A total of 0.09 tracking passes lost data due to severe weather.
A total of 0.28 tracking passes lost data due to the signal from HALCA being late.
