NICER Significant Events


This table list events that may have affected the orientation, data acquitision, or data quality for NICER. It is an important resource for diagnosing unexplained artifacts in the NICER data sets.

Note: ROBO operations (ROBO Ops) can cause obstruction of the NICER XTI field of view for one or more days around the specified activity. Observations within a day (or two) of a scheduled ROBO activity should be checked for possible obstruction of a portion of the XTI field of view. See the analysis thread on ISS obstruction of the XTI field of view for more information.
