Quantile plot depicting the spectral properties of the detected discrete X-ray sources in NGC 45 as listed in Table 6 using a power law grid. Black crosses depict the quantiles for sources as measured from the merged observation while colored open squares show the change in measured quantiles for three sources between the ObsID 4690 and ObsID 6184 observations. The green, magenta and blue squares correspond to the sources CXOU J001406.9–230707, CXOU J001403.6–231006 and CXOU J001356.0–231240, respectively: the lines connecting the pairs of squares help show the change in measured quantiles from one observation to the other. See Section 3.3.
