GraceSstSpecialEvents

Time-indexing deterministic signals in the GRACE K-Band measurements caused by Sun intrusions into the star camera baffles of GRACE-A and eclipse transits of the satellites. The events are determined by satellites' position (inputfileOrbit1/2) and orientation (inputfileStarCamera1/2). Each type of event is represented by its mid-interval point per orbit revolution and is reported in outputfileEvents.

The waveform of each event is nearly constant within one month and can be approximated by a polynomial. For the purpose of gravity field recovery, each waveform is parameterized by a polynomial and the coefficients of this polynomial are estimated as additional instrument calibration parameters in a common adjustment with all other instrument, satellite, and gravity field parameters, see parametrizationSatelliteTracking:specialEffect.
