MCELS derived images of MCSNR J0527−7104. a) [S ii]/Hα ratio map with the colour scale adjusted so only regions of enhanced [S ii] are visible. The SNR is clearly seen with two prominent arcs of enhanced [S ii] located NE and SW of the centre. The emission to the east of the SNR is due to the N 206 H ii complex. b) Continuum subtracted [O iii] image of MCSNR J0527−7104. [S ii]/Hα contours are overlaid, emphasising regions where the ratio is clearly enhanced, ranging from 0.67 to the maximal value with intermediate levels of 25, 50, and 75% of the maximum. The grayscale is in units of 10^-15 erg cm^-2 s^-1. The location of the bright foreground source HD 36877, which was masked for the continuum subtraction, is indicated by the red star. Each image has been smoothed using a 3    ×    3 pixel Gaussian filter.
