Partial 17/34GHz images. Color map shows brightness temperature, contour shows 17GHz (r-l)/(r+l) levels, where 'r' and 'l' indicates right- and left-handed circularly-polarized components, respectively. Field of View is 314. x 314. arcsec
Contour levels of the thick lines are (r-l)/(r+l)=-0.1,-0.2,.. and those of the thin lines are (r-l)/(r+l)= +0.1,+0.2,...
Orange circle at top-left indicates the half-max. beam size
