A specfic EIS study, named GDZ_AR_HOT_1_280X280_SLIT2_50S was designed to include the main lines formed at high temperatures, in particular Fe XVII. They are all weak lines (unless the AR flares) hence the use of 50s exposures, which will saturate the Fe XII 195 line. The study uses a single raster with the 2" slit, a step size of 4" and with 70 exposures covers about 280" in solar X. The extent of the FOV along the slit is approximately the same.
Total duration of the raster: 1h 3m
Total telemetry volume (estimated): 108 Mbits.
------------------------------------------ Details for EIS study definition: ACRONYM: GDZ_AR_HOT_1_280X280 OBJECTIVE: Perform a raster over an active region for cross-calibration with Hinode XRT. Scan a 280x280 area with the 2" slit and a sparse raster, with long exposures (50s) and with all the brightest lines formed at high temperatures, in particular Fe XVII.
