Descripción
The National Center for Atmospheric Research (NCAR) has undertaken a
3-year initiative to develop the Community Spectro-polarimetric Analysis
Center (CSAC). The goal of this effort is to provide the community with
standardized tools for extracting the solar magnetic field vector and
related atmospheric parameters from spectro-polarimetric observations.
The emphasis will be to develop portable, efficient, and well-documented
procedures for analysis of data from the many new and upcoming
observational facilities, both ground- and space-based. The initial
focus of CSAC will be the development of robust methods for inversion of
Stokes spectral data, starting with a standard Milne-Eddington inversion
that has been the workhorse for analysis of data from e.g. the Advanced
Stokes Polarimeter. Upon completion of that code, the program will move
to more sophisticated methods that embrace more realistic and detailed
models of the solar atmosphere. Very fast methods for inversion (neural
networks or pattern recognition techniques, for example) are also
candidates. Finally, the CSAC is intended to eventually provide
standardized methods for resolution of the 180-degree field azimuth
ambiguity, and for visualization of the resulting magnetic field vector
maps. CSAC is formulated as a community effort, and as such will receive
guidance and input from the community.
