Re: Fwd: Ramp data and rising & falling curves

Check for 'warnings' in your .out files. You may see a lot of conververge issues
that SPICE tries to solve. These could lead to the incorrect data points..

Check to see if the datapoints in the .out file makes sense.

You should also be using s2ibis2_fix and not s2ibis.
