There was a total of 25 tracking passes in July of 1998 with 5 of these being unattended tracking passes. Of the 20 attended tracking passes 16 collected the maximum amount of valid data possible. Of the 5 unattended tracking passes only 2 collected the maximum amount of good data. There were 5 tracking passes that lost data due to problems on HALCA or HALCA pointing to the GBES late.
Of the 10 recording passes, 6 collected the maximum amount of good data while the other recording passes lost 9% & 2% of the data due to tape vaccuum problems, 2% of the data due to an s2 controling software bug and 3% of the data due to demodulator problems.
The antenna motor oscillations during the 9807110903 unattended tracking pass would have resulted in the loss of data from the next tracking pass if the next tracking pass was not effected by the HALCA APS not being commanded to look at the GBES.
16 of 20 attended passes had max good data.
Operators helped increase amount of good data in 5 of 5 ``bad'' attended passes.
2 of 5 unattended passes had max good data.
Operators would have increased amount of good data in 2 of 3 ``bad'' unattended passes.
A total of 0.71 tracking passes lost data due to problems with HALCA.
A total of 0.02 tracking passes lost data due to software problems.
A total of 0.53 tracking passes lost data due to hardware problems.
6 of 10 recording passes were completely successful.
A total of 0.17 recording passes lost data.
