There was a total of 20 tracking passes in November of 1999 with 2 of these being an unattended tracking passes. Of the 18 attended tracking passes 16 collected the maximum amount of valid data possible. 1 of 2 unattended tracking passes collected the maximum amount of good data. 9 tracking passes lost data due to the link from HALCA not showing up on time. 4 tracking passes lost data due to twenty or thirty second dropouts of the HALCA signal.
18 tracking passes were observed ``remotely'' from the Jansky Operations Center.
16 of 18 attended passes had max good data.
Operators helped increase amount of good data in 2 of 2 ``bad'' attended passes.
1 of 2 unattended passes had max good data.
Operators would have increased amount of good data in 1 of 1 ``bad'' unattended passes.
A total of 1.86 tracking passes lost data due to hardware problems.
A total of 0.10 tracking passes lost data due to the signal from HALCA being late.
16 of 18 tracking passes observed from the JOC were succesfull.
