Exciting basins with time- and space-dependent potential - keyword SLOPE

Run BALTIC - Free Oscillations, 46 tides possible but switched off.
&param idttep=1 Compute TGP at every time step dt_fixed=90.0 90 s fixed time step etd_slope_opt(1)='N:1.0,84.0,400.0,2.0' A very wide slope, wavelength 400 grid units, cutoff radius twide as wide etd_slope_opt(2)='E:1.0,95.0,400.0,2.0' ... the amplitude could by increased (don't forget higher watchdog thresholds). etd_slope_opt(3)='T:3.,33.,0.25' ... start at hour 3.0, continue for 33 hours, sine period 33/0.25 hours long
(i.e. the slope is suddenly removed)
