This study is designed for velocity studies in and around active
regions. The primary features of this study are: [1] full slit, [2]
relatively deep exposures (60s), and [3] extensive line list. The
current thinking is that the Fe VIII 185 and Si VII 275 lines are the
best lines for velocity calibration.

The planner should (not) put the feature of interest in the middle of
the slit. Using the bottom or top third will provide more quiet Sun
for velocity calibration.

To accelerate the observing and to conserve telemetry a 2" step is
taken between exposures. 

The primary lines for each data window are:

Pointing:
---------
Adjust the pointing so that there is plenty of quiet Sun at the top OR
the bottom of the slit.

Instructions to planners:
-------------------------
** Do not ** put the feature of interest in the middle of
the slit. Put it in the bottom or top third of the slit
so that more quiet Sun will be provided for velocity calibration.

Warning:
-------
2" steps are taken between exposures (sparse raster), 1" slit
