Study 000436:

ACRONYM: VHH_HI_BRT_SCAN_EXT

This study is intended to be run on active region (or quiet sun) to look for
spectral line assymetries and their time variations

The study consists of a single raster, with 8 contiguous positions
of EIS's narrow slit, making a narrow but tall scan with 25-second
exposures at each position. This scanning raster should be repeated 
at least 12-16 times to make an approximately one-hour duration study.

Target: Active region or quiet sun
 
Type:                   scanning raster
Field of view:          16"x240"
Exposure time:          25s
Slit:                   2"
step size:              2"
Study Duration:         4m 8s
Data Volume:            5.6 Mbits

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

Repeat the raster 12 times, at least. Fill the TM slot available

It should be run, where possible, in co-ordinated observations with SOT.
The study is an extension of VHH_HI_BRT_SCAN with slightly altered line
window widths and a larger FOV to make co-alignment with SOT  easier. 
If possible this study should be run  in conjuction with
(VHH_SlowARbig_1h23m) of the surrounding region that has the same line list.

WARNING:
--------

None
