Coronal Multi-channel Polarimeter (CoMP) HeI 1083 nm Images

CoMP observes the solar corona in the forbidden emission lines of FeXIII at 1074.7 nm and 1079.8 nm as well as the neutral Helium emission line at 1083.0 nm. CoMP records full Stokes polarimetry (Intensity, 2 states of linear polarization, circular polarization) over a full field-of-view from 1.04 to 1.35 solar radii. Level 1 and 2 images are 32-bit 620x620, with 4.35 arcsec pixels. Data products include line intensity, enhanced intensity, linear polarization, plane-of-sky magnetic field direction, line width and doppler velocity.

CoMP观测太阳日冕（solar corona）的FeXIII禁发射线（forbidden emission lines）（波长1074.7 nm和1079.8 nm）以及中性氦（neutral Helium）发射线（波长1083.0 nm）。CoMP在1.04至1.35太阳半径（solar radii）的完整视场（field-of-view）内记录全斯托克斯偏振测量（full Stokes polarimetry）数据，包括强度、两种线偏振态及圆偏振态。1级和2级图像为32位620×620分辨率，像素尺寸为4.35角秒（arcsec）。数据产品涵盖谱线强度、增强强度、线偏振、视场平面磁场方向、谱线宽度及多普勒速度（doppler velocity）。
