*J*-band Magnitude \[qualitative\_analysis\_section\]
===========================================================================================================

Here we consider the spatial distribution of CCCP sources stratified by $MedE$ and by $J$-band magnitude that, as seen in § \[contamination\_properties\_section\], are often linked to contaminant classes. We expect that Galactic and extragalactic contaminants will have random locations in the CCCP field, but many Carina members will lie in young stellar clusters. The spatial distributions are shown in Figures \[fig\_aciswith2mass\]-\[fig\_acisno2mass\], with $MedE$ strata informed by Figure \[fig\_me\]. The contours show the distribution of molecular material from NANTEN CO maps [@Yonekura05]. The CCCP sources are further divided into two groups that have or lack 2MASS counterparts, giving two magnitude strata divided approximately at $J \sim 16.5$ mag[^7]. Interpretation of spatial distributions of CCCP sources is confused by the large variations in sensitivity due to overlapping exposures and off-axis angle [@Broos11a]. Our qualitative discussion here is designed to assess the role of contaminants. A more quantitative treatment of spatial groupings from a spatially complete sub-sample of CCCP sources is given by @Feigelson11.

Hard CCCP Sources\[obscured\_section\]
--------------------------------------

In this section we consider all CCCP sources with X-ray median energy $MedE > 2$ keV, equivalent to $A_V \ga 10$ mag [@Getman10]. In panels $d-f$ of Figure \[fig\_aciswith2mass\], $70$% of
