Full sun 17GHz image. The flare region is indicated by the solid box.
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
HXT image overlaid with NoRH contours.
(green/blue) NoRH 17/34GHz brightness temperatures
in logarithmic scale.
Field of View is the same as Partial Image above
Contour levels
are log10(Tb) = 5,6,7,8,...
