Quality Control and
Data Processing

The PIONIER calibration scheme requires a careful match of interdependencies between raw and product calibration files. The calibration products have to be processed step by step; hence this scheme is called a calibration cascade.

• DARK_CALIBRATION (same dispersive element, same gain, same windowing)
• KAPPA_MATRIX (same dispersive element, same gain, same windowing)
• SPECTRAL_CALIBRATION (same dispersive element, same gain, same windowing)
• Astronomical Calibrator: CALIB_OIDATA_RAW and OIDATA_TF (same dispersive element, same gain, same windowing, same vlti setup)

A detailed desciption of PIONIER's association rules is given here.
