This Igor toolkit was intended for use in analyzing AMS data, but there are only few assumptions in the toolkit relating to AMS-type data. Links to Paatero's PMF documentation, including an order form for purchasing PMF from Paatero, and many PMF method papers can be found in Section 9, Other Resources. PMF (Positive Matrix Factorization) was developed by Dr.

Questions about this code can be addressed to Donna. The ipfs were written by Ingrid Ulbrich and Donna Sueper (Jimenez Group, University of Colorado, Boulder) and Greg Brinkman (Hannigan Group, University of Colorado, Boulder). To run PMF with the panel, the PMF executable and associated files, accessed separately, are required (see Section 3, Installing PMF with Igor). This wiki serves as the help and documentation for the software.
The PET consists of several Igor procedure files (ipfs). Please cite the tool with this work in publications in which you have used the PET. The PMF Evaluation Tool (PET) was described in Ulbrich et al., ACP 2009.
