Purpose: Hara and Yoshida visited Dr. Delaboudiniere to see both EIT images
and the calibration laboratory at IAS. The primary objective was
to know the environment of fabricating multi-layer optics for the
future Solar-B mission. We also brought the SXT data there and
compared them with the EIT data after aligning precisely. The
target was to see what kind of structures are seen in each data.
Since the temperature sensitivity of EIT is different from that
of SXT, we paid atention to the spatial relationships between
the structures seen in EIT and SXT. From the relationships we
would like to know the general temperature structures in the
solar corona.

We would like to present what we found in the comparison at ASJ
(Astronomical Society of Japan) meeting and let our collegues to
know that EIT images are important to understand the coronal
structures seen in SXT data. In France, the time for analysis was
limited. We would like to continue the work here under the help by
Jean-Pierre and Gui. The abstract of the ASJ meeting will be sent
to you if you approved this proposal.
