Abstract
I discuss 3 widely applicable aspects concerning calibration of the near infrared adaptive optics integral field spectrometer SINFONI: (1) the accuracy with which one needs to quantify the PSF and how this might be achieved in practice; (2) how it is possible to fine tune the background subtraction to minimise the residual OH airglow; and (3) how an altered perspective on calibration data might lead to improvements in interpolation and greater flexibility in reconstructing datacubes.
