Study: 000619

Updated by M. Whillock, MSSL, 20220624.
Copied from study id 0000544, increased exposure time by 50%.

ACRONYM:  DHB_007_v4

This is a new version of DHB_006 with an expanded line list. It is to be used
for a joint EIS/IRIS spectral scan of the full Sun (IHOP 284).

The study itself is for multiple use, with spectral lines chosen to measure densities,
compute an emission measure distribution to obtain temperatures, and use that
distribution to compute abundances. It covers a very large field of view 
(492"x512") in a relatively short time (was 70 mins) using the 2" slit and 4"
steps. The idea is to fit the raster between SAAs. 

TARGET:           Active Region
EXPOSURE TIME:    45s
RASTER:           Scanning
SLIT:             2"
FOV:              492"x512" 
RASTER DURATION:  1h40m53s 
VOLUME:           72 Mbits
RATE:             17 kbits/s
COMPRESSION:      JPEG90        

The line-list is similar to #218 with Fe XXIV 255 replaced by Si X 261.

Pointing:
---------

As in HOP 130 for a full Sun scan, or any large active region, or AR/CH complex.

Warning:
-------

None.
