资源简介：
UCoMP images the solar coronal in several emission lines with a narrow passband wavelength tunable filter. UCoMP records full Stokes polarimetry (Intensity, 2 states of linear polarization, circular polarization) over a full field-of-view from 1.04 to 2 solar radii. Level 1 and 2 images are 32-bit 1280x1024, with 3 arcsecond pixels. Level 1 data comprises the images of the 4 Stokes parameters at wavelengths across the emission lines. Level 2 data products include maps of line intensity, enhanced intensity, linear polarization degree, plane-of-sky magnetic field direction, emission line width and doppler velocity. Time series of velocity can be used to infer the plane-of-sky magnetic field through coronal seismology.
