Star Mapper calibrations
The star mapper calibrations are important for understanding the Tycho astrometric and photometric data. They also performed a crucial role in the data processing for the Hipparcos data, as the star mapper data were the only source for the across-scan attitude reconstruction, and provided a first approximation of the background level used in the IDT photometry.
The following calibrations can be accessed:
- Geometric calibration
- Residual distributions
- Photometric calibrations
- Background reconstruction (all mission or single orbit)
- Single-slit response functions
