Comparisons of EIS slot (40") and 1" slit rasters with AIA images confirm the estimates
in spatial resolution (3 - 4 arcsec) given above.
The plots below show a comparison of:
a) A 195.119 A slot raster with a AIA/SDO 193 A image convolved with several Gaussians of different FWHM in AIA pixels.

\\
b) a 195.119 A slit raster with a composite of several AIA/SDO 193 A images to mimic the EIS rastering. The AIA final composite image has been convolved with several Gaussians of different FWHM in AIA pixels.

\\
Visually the closest match seems to be around a FWHM of 6 AIA pixels. Given that 1 pixel = 0.6 arcsec, this means a FWHM of 3 - 4 arcsecs.
