Caption: Figure 5.

The color–magnitude diagrams for field sources, low-gravity brown dwarfs and directly imaged planetary mass companions color coded by spectral subtype. Top: M_J (2MASS) vs. (J−W2). Middle: M_J (MKO) vs. (J–K) (MKO). Bottom: M_H (MKO) vs. (H–L) (MKO). In the absence of L-band photometry for brown dwarfs we used the relation in Faherty et al. (2016) to convert WISE W1 photometry to L (MKO).
