You can display the conics using for example show ndlv 2 or show ndlv 4 to 7. Check if all the spots really lie on one or more conics.
By using the command list ndlv, a list of all the conics found will be given. At the end of this list, all pairs -if any- of conics that might be identical are listed. It is a bad sign if a lot of pairs are given: reduce mcombine (minimum is 2) or increase qmin to improve the results, and run NODIRAX again.
