+V0.5:
+13.September, 2023 Gerald Mösenlechner <gerald.moesenlechner@univie.ac.at>
+
+ Fixed Issues:
+
+ - Fixed error with smearing kernel generation
+
+ - Fixed errors in random seed saving
- Known Issues:
+ - Fixed shot noise model
+
+ - Fixed Simulink Bus data types
+
+ - Fixed errors in centroiding algorithm implementation
+
+ - Added Timing tolerance parameter
+
+ - Fixed State preservation
- - No Simulation of "Spaceball" events. Will be added once the effects on the FGS have been studied.
+ - Fixed uninitialized Parameters
+ - Fixed of minor errors
+ - Added Relativistic Aberration
