Objective:
---------

Long duration sit and stare Coronal Hole Observation for HOP103.

Study summary:
-------------

slit:		1"
S/C pointing:	X=0", Y=-945" (off limb)
window height:	512"
exposure time:	500s
# of exposures:	155
duration:	22h 41m 19s
Data Volume:	166 Mbits

Spectral lines:
- density study: Fe XII 195.12/186.85, Fe XIV 264.8/274.2
- kinetic temperature study: Si VII 275.35, Ca XIV 193.87, 
  Fe XV 284.16, Fe XIII 202.04
- comparison with previous UVCS data: O VI 184.00
- core lines: Ca XVII 192.82, He II 256.32

Pointing:
---------

South coronal hole (off limb observations).

Spacecraft pointing: X=0", Y=-945"
EIS Ystart = 1 (cannot use Ystart = 0) (bottom of the CCD).
This implies 16 pixels inside the limb and (512-16) pixels off the limb

Instruction to planners:
-----------------------

Run the folllowing sequence (preferably chained)

1) Run context study (ab_ch_offlimb_cntxt)
2) Run SNS study (ab_ch_offlimb_sands_2)
3) Run context study (ab_ch_offlimb_cntxt)

Run the study CONTINUOUSLY even through the SAAs.

Warning:
--------

Must run through SAA
