Study 000382:

ACRONYM:  GDZ_AR_HOT_1_280X280

Perform a raster over an active region for cross-calibration
with XRT.

Scan a 280x280 area with the 2" slit and a sparse raster,
with long exposures (50s) and with all the brightest lines
formed at high temperatures, in particular Fe XVII.

POINTING:
---------
a quiescent active region observed at the solar limb.

INSTRUCTION TO PLANNERS:
------------------------
Make sure that the XRT images and the EIS rasters are taken 
at the same time. 

Study must be repeated at least 3 times.

Ideally, the study should be repeated twice. Once, when the 
AR is  visible on the disc, and once when it is slightly beyond the limb.

The study should also be repeated at the limb on the quiet Sun, with no 
active regions present.

Fixed pointing is desirable.

WARNINGS:
---------
* The 50s exposure will likely saturate the srongest line.

* Preferably run during SAA-free time period.
