Notes. The FWHM of the observations are measured by fitting a 2D Gaussian to the standard star images taken close in time to the galaxy observations. Fully reduced images are from: 1. Alonso-Herrero et al. (2012). 2. Alonso-Herrero et al. (2016). 3. Asmus et al. (2014). 4. Asmus (2019). 5. Leftley et al. (2019). 6. García-Bernete et al. (2016). The unresolved flux fraction is measured within 1.5 − 1.6″ diameter apertures. When two values for PAMIR − ext (see Sect. 3) are given, the first one corresponds to the inner regions and the second to the outer regions within approximately 1″.
