Cool_loop studies


For 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

This 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

Update 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.
