Note. First row shows the colours directly derived from GROND photometry using the g, r, i, z, J, and H bands in this work. We note that the J, H magnitudes are int the AB system. The second raw lists the colours transformed to the B, V, R, I, J, H bands, as described in Smith et al. (2002) and Blanton & Roweis (2007). The additional rows represent the values obtained earlier in other studies. *: From (Brown et al. 2005) **: Snodgrass et al. (2010) converted to J-H from J − Hs ***: Calculated from V-R and V-I., ****: converted from UKIRT JH to 2MASS JH, using (Cutri et al. 2003)
