Size - mass relation of our sample splitting the galaxy sample according to the image depth on the I-band (F814W filter). We separated those objects that belong to the deeper fields (GOODS South and North) with those from the shallower fields (COSMOS, UDS and EGS). We present the global fits to the entire sample (in green, with the black dashed line corresponding to the local sample) together with those to the deep and shallow galaxy subsamples (red and blue lines respectively). The depth of the different data does not affect to the size evolution of the objects.
