Study 000239: ACRONYM: IUU_SLOT_168X512 It's a modified version of study IUU_SLOT_148X400. It allows more spatial overlap (8") between adjacents pointings. Slot imaging. Five 12s exposures at adjacent pointing positions sampling a 168"x512" FOV in around 70s. 17 repeats totaling around 20min. Spectral windows are selected for their spectral purity, diagnosed from previous 40" slit FULL CCD observations. TARGET : Active region (AR) EXPOSURE TIME : 12s SLOT : 40" FOV : 168"x512" SPECTRAL WIND.: 18 ESTIMATED CADENCE : ~70 s per full FOV. Note : JPEG95 compression. NOTES: To study AR loop dynamics, recommended to run for at least 2h. ********* WARNING ******** Short raster duration (~1m). *** Add 5 seconds per raster repeat to allow for rasters synchronization *** For example: 10 raster repeats. allow a 50 seconds GAP after 10 rasters repeat run (10*5) before inserting a new study on the timeline
