Study 000308:

ACRONYM:  GDZ_LT_PLUME_160x340

OBJECTIVE:

Measure Te, Ne on-disc and off-limb in a plume-interplume 
area in a polar coronal hole. The EIS raster covers 
160"x340" with low telemetry and is designed to have transition 
region lines, with a few  hotter ones aswell. 


TARGET        : Coronal hole region
EXPOSURE TIME : 40s
RASTER        : Scanning
SLIT          : 2"
STEP_SIZE     : 2"
FOV           : 160"x344"
SPECTRAL WIND.: 16
DATA COMP.    : JPEG90
RASTER DURATON: 58m 37s
DATA volume   : 51 Mbits  
LINES         : He II, O V, O VI, Si VII, S VIII, Si X, Ca XVII
                Fe VIII X,XI,XII,XIV,XVI, XXIII


POINTING:

The pointing should be such as the base of a plume inside 
a coronal hole region is observed, as well as its extension off-limb.
Make sure that the base of the plume is observed by SOT.


INSTRUCTION TO PLANNERS:

Shift the EIS CCD window (Y-direction) if needed to adjust the pointing.

It is important to coordinate with TRACE planners so TRACE 171 A band 
is observed during the same period of observation. 


WARNING:

None
