Thanks Hugo! If you send me an email (email@example.com), I can put you in touch with Melissa at the SEG who can help arrange a certificate for you.
As for photos, we have a few up on instagram: http://instagram.com/geosci.xyz/ and we are working on a blog about the presentation in Brazil, so stay tuned!
SEOGI KANG: the PropMap was our first crack at that (being able to invert for either / both sigma and mu), but at that point, we were still stuck with the inversion model having to be a physical property. Once we removed the PropMap and started working with properties, we now have more options for playing with what you can invert for.
