VLT/FORS2 g-band imaging of the host galaxies for (from top to bottom) FRB 180924, FRB 181112 and FRB 190102. The left-hand column is the first epoch image, and the right-hand column is the difference image resulting from the subtraction of the second epoch from the first. Red ellipses show the uncertainty on the FRB position in each case. Colour bars show the pixel values of the difference image, in units of standard deviation from the mean. The bars in the lower-left corner of each image show the image scale. In the left column, they are fixed at 1 arcsec; in the right column they are set to the greater PSF FWHM of the two epochs used in subtraction, which corresponds to the effective PSF of the difference image.
