     61I had a go at re-stacking skycell 077 (g-band) for MD08. I had to chuck away frames with bad readout problems, and then applied a simple background subtraction (sans objects). Below is the comparison to the PS stack -- it seems cosmetically better, but I'm not sure about the depth yet. Note this was the stack of the warped frames - I applied a median combination with 3-sigma clipping.
