We then plan to do line_4: spectroscopy with the slit along two axes: line_6: - first, through the radio knots at PA = 168 degrees line_8: - second, either through the nucleus at PA close to 45 degrees (inner HI line_9: major axis) if the extension of gas is large enough in this direction, line_10: or again at a PA close to 168 degrees with a small off-set from the line_11: nucleus (a value of ~135 degrees, PA of the minor axis of the inner HI line_12: distribution, would be of interest to investigate radial motions). ! question: 4 section: 1 line_1: The long-slit spectrograph of the FOC provides an unprecedented angular line_2: resolution. ! question: 5 section: 1 line_1: A direct imaging observation is required first to determine the precise line_2: location of the nucleus and to allow a fine tuning of the slit position angle. ! question: 10 section: 1 line_1: Data analysis capabilities. ! question: 13 section: 1 line_1: Long-slit spectroscopy of the nucleus of the galaxy MK348.
