Effect of a customised versus circular random sample on the TPCF of young SFCs in NGC 5457: Even though the l_corr value is found to be nearly the same in both the cases, the first power-law slope is found to be shallower for a circular random sample. The absolute correlation and the slope of the second power law are found to be considerably higher in case of circular random sample. In the left panel, green contours mark the customised footprint within which random points are populated. In the left and central panel, purple stars and cyan dots represent the true SFC positions and the random points generated for TPCF calculation, respectively.
