There was a total of 17 tracking passes in February of 1998 with 10 of these being unattended tracking passes. Of the 7 attended tracking passes 7 collected the maximum amount of valid data possible. Of the unattended tracking passes 5 of 10 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 1-3 of 5 passes. There were 4 tracking passes where there were problems with HALCA and 3 tracking passes where there were problems with the SRT files or orbit prediction files.
Inclement weather caused the complete loss of one tracking pass. The observatory was on emergency shutdown and the operator did not notify GIL or AHM that he was not attending the tracking pass. The tracking pass could have been performed due to the low elevation of HALCA during the whole tracking pass without any danger to the safety of the NRAO OVLBI earth station.
Of the 2 recording passes, 2 collected the maximum amount of good data. One recording pass was affected by the SRT file not reflecting the current orbital parameters after HALCA came out of a safehold mode.
7 of 7 attended passes had max good data.
Operators helped increase amount of good data in 0 of 0 ``bad'' attended passes.
5 of 10 unattended passes had max good data.
Operators would have increased amount of good data in 1-3 of 5 ``bad'' unattended passes.
A total of 0.03 tracking passes lost data due to software problems.
A total of 0.07 tracking passes lost data due to hardware problems.
A total of 4.00 tracking passes lost data due to problems with HALCA.
SRT and orbit prediction file problems resulted in the loss of 0.84 tracking passes.
2 of 2 recording passes were completely successful.
A total of 0.00 recording passes lost data.
