Co-spatial and co-temporal observations of active region NOAA 12393 with the SST, IRIS and SDO/AIA. a) TRIPPEL raster scan image in the continuum at 1081.971 nm. b) TRIPPEL raster scan image of the profile minimum of He i 1083 nm. c) TRIPPEL raster scan image of the equivalent width of He i 1083 nm. d) Artificial raster scan constructed from the IRIS 140 nm SJI images which are dominated by Si iv emission. e) same as d), but now smoothed to AIA resolution. f)−i) artificial raster scans for the AIA band given in the panels. j)−k): same as c), d), and f), but now with contours of local maxima in the EW overplotted in red. The blue box outlines the area discussed in the text.
