Fig. 2


H-band magnitude of sources detected within the X-ray error circle (measured on 2010 Aug. 30) vs. the magnitude difference between the Aug. 30 and Aug. 31 epochs. The objects with Δm > 0 mag are brighter in the second epoch. Sources marked as “ABCD” show variability greater than the observed dispersion for objects with similar brightness. Errors are at 1σ c.l., magnitudes are in the Vega system and uncorrected for Galactic extinction.
