82. Description
... The wavelength calibration is provided in two tables, one per grism, containing the value of the wavelength corresponding to each pixel in the extracted spectrum, counted from the centroid of the spectrum zero order in the undistorted and rotated image. ...

... The task omgprep prepares the OM grism image for detection and extraction of spectra (introduces distortion corrections, properly rotates the image, etc.) ...
85. Description
... The angles are to be interpreted as 3-2-1 Euler rotation angles[ 2 ] through which the SACCOORD frame is transformed into the instrument boresight (IBS) frame as depicted in Fig. 1 for the case of EMOS2. ...
86. Description
