This is the same study that is used for HOP 81. It performs a large scan of the polar region in coordination with SOT/SP measurements of the magnetic field.
TARGET : Coronal hole
EXPOSURE TIME : 50s
RASTER : Scanning
SLIT : 2" (was 1")
STEP_SIZE : 4" (was 1")
FOV : 322"x384"
SPECTRAL WIND.: 24 (was 12)
DATA COMP. : DCPM
RASTER DURATON: 1h14m
DATA VOLUME : 140 Mbits (was 150 Mbits)
LINES : Fe VIII, Fe X, Fe XI, Fe XII, Fe XIII,
He II, O V, Mg VI, Mg VII, Si VII, Si X
Fe IX, Fe XIV, Fe XV, Fe XVI, S X, Ar XI
Polar coronal hole with fixed pointing.
Make sure to cover SOT FOV and the solar limb.
INSTRUCTION TO PLANNERS:
Start this study at the beginning of the SAA free period (roughly 10-15UT). Repeat the study several times avoiding Hinode eclipses. The later part may coincide with a short SAA.
Note: The plan for FSM is the same as that for DSM.
Avoid SAAs as much as possible (SAA degrades data compression factors and mutilates the data)
