Examples of spectrally resolved PMJs. Panel a: photospheric CHROMIS wideband reference image (center wavelength 395.0 nm and bandwidth FWHM = 1.32 nm). Panel b: CHROMIS Ca II K image at a Doppler offset of −12 km s⁻¹. Panel c: CHROMIS Ca II K image integrated over the full sampled spectral profile, convolved with a Gaussian profile with FWHM = 0.1 nm. Panel d: similar integrated CHROMIS Ca II K image, convolved with a FWHM = 0.3 nm Gaussian, and giving enhanced weight to the two outer scan positions. Panel e: CRISP Ca II 854.2 nm image at a Doppler offset of −16 km s⁻¹. The red crosses in the images mark the spatial location in the PMJ for which spectral profiles are shown in panels f and g. The thick solid lines in panels f and g show the Ca II K and Ca II 854.2 nm PMJ spectral profiles, and the red crosses mark the spectral positions of panels b and e, respectively. The gray lines are reference spectral profiles averaged over a region outside the active region. Panel f: horizontal lines of width 0.3 and 0.1 nm as reference to the FWHM bandwidth of the Hinode and SST imaging filters. The inset in panel f shows a Ca II H spectral profile from the FTS atlas (Neckel 1999) against Doppler velocity offset. The dashed lines are Gaussian profiles with FWHM = 0.3 and 0.1 nm.
