Colour image of M61 compiled from three narrow-line maps used in this survey; red, green and blue colours correspond to [SII], Hα and [OIII], respectively. The background image is the collapsed cube of the MUSE observation. White circles and numbers are the SNRs in the galaxy confirmed by this survey. Magenta stars indicate the locations of previously observed SNe in the field of view. Gold stars show the locations of the three O-rich SNRs in the galaxy. Corresponding stamps of the other host galaxies are available here.
