II. Stokes Profiles and Vector Field Samples in Sunspots Hewagama, Tilak ; Deming, Drake ; Jennings, Donald E. ; Osherovich, Vladimir ; Wiedemann, Gunter ; Zipoy, David ; Mickey, Donald L. ; Garcia, Howard Abstract Polarimetric observations at 12 microns of two sunpots are reported. The horizontal distribution of parameters such as magnetic field strength, inclination, azimuth, and magnetic field filling factors are presented along with information about the height dependence of the magnetic field strength. Comparisons with contemporary magnetostatic sunspot models are made. The magnetic data are used to estimate the height of 12 micron line formation. From the data, it is concluded that within a stable sunspot there are no regions that are magnetically filamentary, in the sense of containing both strong-field and field-free regions.
