Same as Fig. B.1 but for the LRS2 PSF characterization. We show the size measurements of the standard star BD+210607 observed at the end of the night of the J0804+4726 observations. We do not include a rotation measurement because most of the standards stars can be considered as circular (see Fig. B.3). The size of the stars as observed with LRS2 and therefore the LRS2 PSF is better described with a Moffat model.
