-Although this is the best example in the database because of the density of measurements and the known small amplitude of any lightcurve, we may be misled because of the slow motion of the object causing problems in brightness measurements. This will occur if MOPS is being fed warp-warp measurements instead of warp-stack. The variation in z-band in the plot below is puzzling:

But this will only occur if MOPS is being fed warp-warp measurements instead of warp-stack, and it should make the object fainter, not brighter as seen. The variation in z-band and in other filters in 2012 is also puzzling:
