Study 000047:

Consists of three rasters:

(1) a context raster covering 40x304 arcsec2 with 1" slit
(2) sit-and-stare with 1" slit taking 304" along slit (100 exposures)
(3) repeat of context raster

Exposure times are 5 seconds, and five lines are included: the core
lines plus the Fe XIII 203.8/202.0 density diagnostic.

USE: The aim is search for high cadence density variations in active
regions.

NOTES: the number of repeats of (2) should be adjusted to fill the
available time slot.

WARNING: because of the 2nd context raster (3), care has to be taken
that the change from (2) to (3) does not take place during an SAA. For
this reason the planner is requested to run the study
PRY_fast_dens_v2.
