Study: 000604

ACRONYM: CH_Funnel+FIPv2

Purpose:
-------
The aim of the study is to track and analyze the open magnetic funnels in an entire on-disk
coronal hole from the photosphere to the low corona. The observations are coordinated between
GREGOR, SST, IRIS, and Hinode. The Hinode/EIS data will be used to derive FIP ratio maps,
outflow maps, and density maps in multiple layers in the transition region and low corona. 
High-FIP elements in this study are O and S, low-FIP elements Fe, Si, and Mg.

TARGET:
-------
full low-latitude coronal hole, or low-latitude extension of a polar coronal hole,
respectively, including its boundary region to the quiet-Sun

Pointing:
--------
Entire low-latitude coronal hole, or low-latitude extension of a polar coronal hole,
respectively, including its boundary region to the quiet-Sun.

Instruction to planners:
-----------------------
The study shall scan an entire coronal hole including its nearby boundary region in
consecutive tile windows. Each tile window has a size of 130x512. Presuming a usual coronal
hole of a size of ~300"x400", 3 tile windows would needed to be scanned; but the number can
vary depending on the size of the coronal hole. The scans shall be performed outside of SAAs.
Due to the extensive line list and resulting large data volume, the off-limb allocation for
EIS is requested. 
 
Warning:
--------
High data rate, high data volume
