Community Spectro-Polarimetric Analysis Center (CSAC)
Figure 1: Results from a MERLIN inversion
of Hinode data obtained on 11 December 2007 are shown. The continuum
intensity showing the sunspots is at upper left. This active
region shows a channel of (upper right)horizontal (inclination &126;90° lower right) magnetic flux running from lower left to upper right, corresponding to a filament in the chromosphere above. The fields are oriented roughly along the channel (field azimuth, lower left). These data suggest that the flux forming the filament results from the emergence of a rope of
magnetic flux.

The Community Spectro-Polarimetric Analysis Center (CSAC) Strategic Initiative was conceived to strengthen HAO's position in the rapidly growing spectro-polarimetry community and also to transfer its 30+ years of heritage and leadership in the field to the broader community. CSAC is providing support for a host of new instruments for measuring vector magnetic fields in a range of solar atmospheric layers. Its most significant contribution to the broader community is the development and distribution of a modular suite of "standardized" (numerically robust, accessible, well-documented, and portable) computer analysis and data visualization codes that will be applicable to past and future spectro-polarimetric instrumentation.
During FY08 CSAC implemented the MERLIN (Milne-Eddington gRid Inversion Network) code as the workhorse analysis tool for data from the SOT/SP instrument on board of the Japan/US/UK Hinode spacecraft. These data receive the highest visibility and usage in the solar community. MERLIN output for SOT/SP is now being released through the CSAC web client. In FY2008 CSAC also begun standardizing the next-generation analysis tool LILIA (LTE Inversion based on the Lorien Iterative Algorithm) which will allows users to derive more detailed information about physical conditions in three dimensions within the Sun's magnetic photosphere by utilizing a more realistic atmospheric model.
In addition, work has begun on development of CAZAM (CSAC AZimuth AMbiguity utility), to visualize the vector magnetic field information produced by these codes. Current User Group: The CSAC user group currently consists of researchers from twenty institutes across the world.
