Mapping of DIII-D Profile Data in OMAS*

A common task for any tokamak core transport interpretive analysis is the fitting of the kinetic profiles with a smooth curve. In One Modeling Framework for Integrated Tasks (OMFIT), the OMFITprofiles module has grown a large number of methods to fit the data with a curve. In addition, the OMFITprofiles module is able to fetch data from a variety of devices and data structures for fitting. One data type to which OMFITprofiles has not been completely adapted is the ITER Integrated Modeling and Analysis (IMAS) data structure, which should be able to handle any device and data format where the data is stored in the IMAS data schema. The Ordered Multidimensional Array Structure (OMAS) library (gafusion.github.io/omas) contains methods for converting data stored in MDS+ to the IMAS data structure. The ability to map DIII-D profile data is being added to the OMAS library, and the best default methods and parameters for OMFIT profile fitting are explored.
