ODR has been discussed before on this newsgroup. I'm not aware of any
package in IDL. A curve fitting program like MPFIT would need to be
modified pretty significantly to accomodate the ODR aspects. [*] In
the past I've referred people to ODRPACK and they've been very happy
(except that it's not native IDL).

[*] - actually, the changes are not huge. It might be an interesting
project for someone.
