Study 000571:

Acronym: ar_vel_fast_scan

The goal of this study is to track the evolution of plasma velocity in loop
footpoints, in order to detect possible periodical up and downflows.
Therefore this study is to be repeated over several days.

To that end, cadence of about 40 minutes is used, with medium exposure times
(30 s) and a sparse scan (4" step). Since we do not know in what footpoints the
pulsations could occur, the study features a wide FOV (300"x512").

Pointing:
---------
The FOV should contain a full bundle of loops (including both footpoint
regions). In addition, a quiet Sun region at the top or bottom of the FOV would
be very helpful for the velocity calibration.

Instructions to planners:
-------------------------
Repeat the study run if more TM become available

Info. to be added.

Warning:
-------
4" steps are taken between exposures (sparse raster)
