wavelet transformed XAS in Larch-0.9.24
Dear mailing list user, I am currently trying to use the cauchy_wavelet.py plugin of Larch-0.9.24 to wavelet transform some k-space EXAFS data. In principle, everything works properly, but I would like to adjust the order of the Cauchy wavelet to 50. However, a view inside the script does not make clear what changes are necessary. How can this be done? Please provide me your suggestions, Many thanks, Matthias Filez PhD student Ghent University / Laboratory for Chemical Technology Technologiepark 914, B-9052 Ghent - Belgium http://www.lct.UGent.behttp://www.lct.ugent.be/ Disclaimer: http://helpdesk.UGent.be/email/disclaimer.phphttp://helpdesk.ugent.be/email/disclaimer.php

I'm not sure. There are many possible variations of wavelets, and I am by no means an expert in them. I think the variation used in Larch's cauchy_wavelet.py is similar to the one from Munoz et al (and the ESRF Hama code too -- correct me if I'm wrong about this!). Perhaps there is an alternate definition on Cauchy wavelet that has such an order? I think it would great to have more than one version of wavelet transforms available... --Matt
