HOPs 266 and 267 I designed some studies with the prefix "cool_loop",
and I briefly describe the differences between them here.
Temperature coverage is essentially capped at Fe XVI, and so these studies are not good for flare observations.
Cool_loop_response, (ID 444; Cool_lines_v6)
Data rate: 2369 Mbit/day
This was intended as a response study, i.e., a hunter study
(usually Hunter_loop_fe8) is run to find the brightest footpoint
region, then Cool_loop_response is run automatically at this location.
However, Cool_loop_response can be run as a standalone study too.
It covers an area of 90" x 144" with 3" steps and 20s exposures. The line list has an extensive set of cool lines.
Cool_loop_narrow (ID 529, Cool_lines_v8)
Date rate: 1315 Mbit/day
is a higher cadence study than Cool_loop response, covering 36"x144" in
7 minutes, with 30s exposures. The number of coronal lines was reduced
and the exposure time increased to get a lower data rate.
Cool_loop_stare (ID 527; Cool_lines_v9)
Data rate: 1564 Mbit/day
A sit-and-stare study intended for HOP 266. It takes 184"
along slit and uses 30s exposure to compensate. The line list is the
same as Cool_loop_narrow, only Fe XII 193.51 has been added.
Cool_loop_resp_v2 (ID 528, Cool_lines_v7)
Date rate: 1913 Mbit/day
to Cool_loop_response with a larger FOV of 120"x184", and with the
reduced line list of Cool_loop_narrow (only the Si VIII lines at 277
angstrom were added).
Cool_loop_stare_v2 (ID ???; Cool_lines_v10)
Data rate: TBD
An update to Cool_loop_stare to take advantage of the
increased data rate since the failure of the SOT filtergraph. Only the
line list has changed: the line list of Cool_loop_response is used with
16 pixel windows increased to 24 pixels; Fe XII 193.51 is added, and
the Mg V 276.58 window is expanded to include the Si VIII lines at 277.
