delta invariant of a space curve

Hi,
is there a procedure to compute the delta invariant of a space curve which is given by an ideal?
Thanks,
Konrad

Dear Konrad,

you may try the command normal (from normal.lib):

normal(J,"wd") (J the given ideal)

computes the normalization and the delta invariant (on its way).
