The I_Stokes image displays the intensity in each specific band in units of thermodynamic temperature (K_CMB) for 30-353 GHz and in surface brightness (MJy/sr) at 545 and 857 GHz.

The Q_Stokes and U_Stokes images display the polarized brightness in the corresponding Stokes parameters, in units of thermodynamic temperature (K_CMB).

The Hits image displays the number of observations falling within each HEALPix pixel.

The II_Cov, QQ_cov, and UU_cov images display the variance in the corresponding Stokes parameter images, in units of K_CMB2 for 30-353 GHz and in (MJy/sr)2 at 545 and 857 GHz.

The IQ_Cov, IU_cov, and QU_cov images display the covariance inbetween the corresponding Stokes parameter images, in units of K_CMB2 for 30-353 GHz.
