ACRONYM:HH_Flare_180x160_1

This study is used to hunt for various flow structures in solar
flares. It can also be used for studies of the active regions. 

Target: Active region

Type:			scanning raster
Field of view:		180"x160"
Exposure time:		8s
Slit:			2"
step size:		5"
Raster Duration:	6m 13s
Data Volume:		4 Mbits

lines:

O VI: detection of TR response at the impulsive phase
Fe X: hunting of reconnection inflow
Fe XII: hunting of reconnection inflow
Fe XIV: study for normal coronal loops with density sensitive pairs
Fe XV : study of flare loops in a cooling phase
Fe XVI: study of flare loops in a cooling phase
Fe XVII:  study of flare-loop heating  and reconnection outflow
Fe XXIII: study of loop-top hot region and reconnection outflow
Fe XXIV:  study of loop-top hot region and reconnection outflow

The non-thermal velocity component in solar flares is
studied by combinations of Fe XXIII and Fe XXIV.

Pointing:
---------

Active region including those with the potential for flaring

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

1) Centre the raster on an active region
2) When flare hunting, adjust the raster repeat for a maximum run-time
possible, accounting for the TM constraint.

Eg:
Raster repeat: 160
Run time: 16h 30m
Data volume: 782 Mbits (JPEG85)
Data Volume: 635 Mbits (JPEG75)
 
Note: When the telemetry is limited, change the compression parameter
from JPEG85 to JPEG75. If in doubt, consult:

WARNING:
--------

Do not adjust the data compression below JPEG75
