In comparison with the\nSDSS DR9 and 2MASS, we obtain the following upper limits (3-sigma):\n\n  r     > 22.99\n  i     > 22.59\n  Z     > 21.59\n  Y     > 21.14\n  J     > 20.82\n  H     > 20.49\n\nThese magnitudes are in the AB system and are not corrected for Galactic\nextinction in the direction of the GRB.",
