CSAC GOALS

Provide a common repository for spectro-polarimetric (SP) data analysis software.

Data Reduction Routines: Develop software for flat-fielding, polarization calibration, merging, rectification, fringe removal, etc. to prepare data sets for subsequent inversion.

Milne-Eddington Inversion: This is the workhorse of analysis of SP data to extract the magnetic field vector (and other associated properties of the magnetized atmosphere).

LILIA Inversion: Develop standardized, portable software based upon the Stokes Inversion by Response functions (SIR) procedure. This technique allows for variation of parameters along the line-of-sight.

Rapid Inversion Techniques: We will investigate new techniques to develop rapid SP analysis tools. Principal Component Analysis, neural networks, and support vector machines offer meaningful inversions at a very large increase in speed.

Ambiguity Resolution: CSAC will serve codes for resolution of the 180º azimuth ambiguity.

Data Visualization: We will provide the AZimuth AMbigiuity (AZAM) utility, as well as other methods for visualization, which will be maintained by CSAC.

Promote community involvement in and access to investigations.

Instrument Development: Develop and build the next-generation of SP instrumentation e.g., the Diffraction Limited Spectro-Polarimeter (DLSP), the Spectro-Polarimeter for Infrared and Optical Regions (SPINOR) and the Prominence Magnetometer (ProMag).

Workshops & Meetings: Will support and host community workshops to advance the understanding of spectro-polarimetric measurements.
