Too many points in pre-edge
Matt: I am running into a somewhat annoying problem with continuous scan data imports into athena where there are many datapoints before the edge (I think > 400 or so). With these files, the location of the edge (and element identification as well) using the first derivative does not work. The edge is identified as being somewhere in the pre-edge. As I reduce the number of data points in the pre-edge, the edge identification moves closer to the true edge and then locks in correctly when the number of data points in the pre-edge is small enough (again, I think this is less than 400 points). I can address this problem by running these data through a rebinning process in the pre-edge but I think that if it is possible to handle this in ifeffit, that would be a good idea. On a second note, would you tell me whether you or Bruce is planning to maintain the ifeffit perl wrapper? At this time, ifeffit 1.2.6a and horae 046 have different versions of the Ifeffit.pm script (1.3 and 1.301 respectively). I recently ran into a problem because I had the ifeffit version and horae 046. Carlo -- Carlo U.
