Study 000183:

ACRONYM: STA_loop

Objective:
----------

to investigate the morphology of coronal loops which support longitudinal
intensity perturbations, the nature of the (quasi-) periodic driver and
the evolution of the perturbation as they travel through the different
temperature regions of the solar atmosphere.


Conditions Necessary to Run & Pointing:
---------------------------------------
Occurrence of a relatively quiescent (non-flaring) coronal loop system
either on the disk or limb. Involvement of, at a minimum, Hinode/EIS,
SOHO/CDS and TRACE. Additional support from Hinode/XRT and Hinode/SOT/FPP

NOTES to planners:
-----------------
(i) The planner should use the study as defined, with one 'StA_loop
2" raster, followed by n repeats of 'StA_loop1' raster to fill the available
time slot.

(ii) The planner should not repeatedly switch between these
rasters 1 and 2 in a study during a SAA would be extremely beneficial. 

(iii) When being run as part of a JOP, the high-cadence (single slit) runs
of Hinode/EIS should occur at the same time as the TRACE and Hinode/XRT
high-cadence runs.
