[Ifeffit] negative e0 value

[mauricio.maps]

Dear all,
I´m trying to deal with exafs data of a Ni-phosphate compound, using
Athena/Artemis. This is a simple structure (I think), with the
hexacoordinated ion surrounded  by water molecules on the first shell. The
question I have concerns the negative value for e0 I´m having.
Is this a bad thing?
Maybe I´m doing something wrong?
I´ve tried some issues, as those proposed on the Shelly Kelly´s tutorial,
but without success.
Can you help me, please?
Attached are an example of the Athena and Artemis projects i´m using.
Thanks a lot.
Mauricio
