I don't have access to JCPDS cards, but I can compare the obtained pattern with Crystallographic information files (CIFs) deposited in crystallographic databases, by using Rietveld Refinement method. It gets the same effect as compare with a JCPDS card, but if you really need this card, there are people around that will came up with what you need. Let me know if you want to do a Rietveld refinement, I can help with this.
