The FOV MUST BE large enough to cover the entire AR and some boundary region around it.
One new EIS study has been designed and now modified: GDZ_300x384_S2S3_40s 2" slit, 3" step, covers 300" in less than 1 hour. 380" extraction along the slit means 360" co-spatial data from the SW and LW channels.
40s exposure will saturate in some points the Fe XII line, however thw Fe XII 192.4 line is also included in the study.
Selection of lines: a few spanning all temperatures including core lines, lines to deblend them, and flare lines: He II (core), Fe VIII (Si VII, Mg V, VI, VII), Fe X, Fe XI, Fe XII (core), Fe XIII, Fe XIV, Fe XV, Fe XVI, Ca XVII(core) Fe XVII, Fe XXIII, Fe XXIV.
Details of EIS Study Definition:
ACRONYM: GDZ_300x384_S2S3_40s
OBJECTIVE:
Perform a large (300x384) sparse (3") raster over an active region with the 2" slit and long exposures (40s). TARGET : Active region EXPOSURE TIME : 40s RASTER : Scanning SLIT : 2" STEP_SIZE : 3" FOV : 300"x384" SPECTRAL WIND.: 25 DATA COMP. : DCPM RASTER DURATON: 1h14m DATA volume : 182 Mbits LINES : Fe VIII, IX, X,XI,XII,XIII,XIV,XVI,XVII, XXIII, XXIV O V, Mg VI, VII, Ca XIV, XVII
POINTING: a quiescent active region observed across the disk.
INSTRUCTION TO PLANNERS: It is important to inform CDS planners of the EIS pointing so that the study ARCONT (ID 11, VAR 105) containing the Fe XIX and Ne VI lines is run. |
