Two-dimensional plot of deviation. The colour bars in all the panels represent the values of the deviation in kpc from the best-fit plane to the SMC disk. The sample that shows absolute deviation larger than 6 kpc are considered as outliers from the plane, which implies that the sample with deviations in the range − 6 kpc to +6 kpc is on the plane. The closer sample is that which shows deviation larger than +6 kpc and the farther sample is that which shows deviation less than − 6 kpc.
