Re: active region birth/death?
Dear Mark san,
Do you have any quantitative information about the diameter of the
gaussian core of PSF for the Al/Mesh filter and the other filters?
I'm analyzing the temperature above the south pole limb taken during
the eclipse on February 17, 2007. We used Al/Mesh and Ti/poly for the
Just on the limb, the temperature is high, but emission measure is low
(See the attached PNG file). This may be a spurious structure caused
by the diffuser image of Al/Mesh than the Ti/Poly image.
The attached plots shows the several profiles in the south pole as the
function of the distance from the sun center (limb=1).
- The upper pannel shows the intensities: Al/Mesh(red) and
- The center pannel shows the temperature.
- The lower pannel shows the emission measure.
