Study 000452:

ACRONYM: YKK_EqCHab_160x512

This study is one of the two studies (the other is YKK_EqCHab_st) designed for measuring the
temperature, density, and abundances in and above an equatorial or low-latitude coronal hole
during the STEREO-Earth quadrature period. 

TARGET:           Coronal Hole
EXPOSURE TIME:    200s x 2
RASTER:           Scanning
SLIT:             2"
STEP SIZE:        4"
FOV:              158"x512"
RASTER DURATION:  4h49m41s
COMPRESSION:      DCPM
VOLUME:           158.5 Mbits

Pointing:
---------

Target (ToO):
A equatorial or low-latitude coronal hole when it is passing the east limb, the central
meridian and the west limb 

Use/Instructions to planners:
-----------------------------

Run once when the coronal hole is passing the east limb, the central meridian or the west limb.

Pointing: 
East limb passing: X= -950", Y= above the target coronal hole
Central meridian passing: FOV in X covering 2/3 of the coronal hole, 1/3 of the quiet Sun at
                          its east boundary
West limb passing: X= +950", Y= above the target coronal hole
             
Warning:
--------
None.
