IFS distortion frame contains the IFU spectra of a pinhole mask

IFS_DIST_RAW1 IFS_DISR_RAW2 Left: IFS of the pinhole mask. Right: zoom of the left image.
IFS_DIST_PRO2 IFS_DIST_PRO2 Left: cube reconstructed and collapsed image of the pinhole mask. Right: optical distortion polynomial function extracted from the comparison between the left image and the POINT_PATTERN static calibration containing the pinhole nominal positions.
