# This file contains the offset between the line of sight given by the
# star trackers (deduced from the S/C quaternion), expressed as (X,Y)
# coordinates in the CCD reference frame RCCD, and the line of sight of the
# reference pixel. It must be calibrated from observations of star fields, and
# is subject to variations due to thermoelastic displacements of the S/C and
# of the instrument. The accuracy is about +/- 10 pixels in X (first line)
# and +/- 3 pixels in Y (second line).
#
# The third line contains the difference between the ROLL angle of the S/C
# (deduced from the S/C quaternion), and the actual ROLL angle of the camera.
# The NAC ROLL angle is counted counterclockwise on level 2 images.
