Introduction

• The graphical event sequence is a visual time hist

sensor infor

–

Covers approximately 8 minute timeframe, from first anom

through last available telemetry

–

Documents known anomalous sensor responses per the la

timeline fro

• Information contained in the graphical event sequ

–

Sensor location on orbiter and its associated wire bundle in 

–

Description of each anomalous sensor event

–

Time annotation by (a) GMT, (b) time relative to LOS, (c) t

ground track
