摘要：
We present high resolution imaging spectroscopy measurements of sunspots observed at the NSO/Dunn Solar Telescope using Adaptive Optics, and a cascaded, tunable dual-Fabry Perot imaging interferometer system. Using this instrument we have observed sunspots in the FeI 5576Angstrom spectral line, and simultaneous G-Band images. We present thermal and velocity measurements of two sunspots: NOAA 9268 observed on December 19, 2000, and NOAA 9451 observed on May 10, 2001. We present intial results from fitting intensity profiles using the Stokes Inversion based on Response Functions (SIR).
