Detailed description of the data product¶
PSF Level2 Calibration parameters, giving the current state of the telescope after fitting to defocused and infocus data at multiple solar angles and roll angles.
Will include a basis set of Zernike amplitude/telescope optical layout parameters which describe wavefront propagation through the system, expected to consist of < 100 params (floats).
Detector state format TBD, will include parameters describing the brighter-fatter effect, chip-to-chip variation.
Will contain parameters describing the FOV-dependent mapping between the telescope model (optical layout) and zernike amplitudes, as a list of coefficients to a polynomial fit. TBD.
