STM Eigendecomposition
The eigenvalues and eigenvectors of the 6x6 cartesian State Transition Matrix (STM), formatted as text for better readability. The STM describes the effect of position-velocity perturbations made at the start of propagation on the position-velocity state at the reported time. The coordinate system of the STM is required pre-data. Updated data is generated only for segments with a propagator that has a State Transition Matrix propagator function. When accessing after the MCS has been run, the eigenvalues are sorted for consistency between ephemeris points. When accessing during an MCS run, the eigenvalues are sorted by absolute value of the real part.Available for these objects: Satellite
Restrictions: Satellite - Applies when Satellite is propagated using Astrogator and uses a State Transition Matrix propagator function.
Type: Time-varying data.
Availability: Reports | Graphs | Dynamic Displays | Strip Charts
Pre-data required: "<TruncObjectPath> <SystemName>" - e.g. "CentralBody/Sun ICRF"
