During the course of Chandra operation, there were several incidences which caused a sudden jump on
trending envelopes. The table below lists all incidences we used in the trending. If the cause is
clear, we indicated in the second column. A system named in the "affected systems" column is linked
to a list of msids of that system so that you can see which msids are affected by that incidence.
