... The calibration of astrophysical spectra in wavelength based on calibration lamp data suffers from different kinds of uncertainties. Besides inaccuracies in the observational phase, common data reduction practice adds ``pixelation'' errors, due to the fact that the centering method does not use the correct PSF. These model mismatch errors depend, for a given feature, on the sub-pixel location of the line center (David & Verschueren, private communication). ...

To main of Laboratory . The research work and design of optical and optical-electronic devices are carries out by laboratory staff: . ... Lens: . ...

Next: PSF1DRB Up: PIXTOPIXSENS Previous: Generation from Ground Calibration Contents . Ideally the in-orbit PixToPixSens file will be generated from internal calibration measurements using the fullframe high resolution engineering mode. However due to their large data volume the fullframe high resolution data won't be available frequently enough to base the in-flight generation of the PixToPixSens file on the high resolution data. ... i.e. the average counts per pixel per CCD-frame . ...
