v31 v32 59 59 == Stacking tests == 60 60 61 I 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. 61 I had a go at re-stacking skycell 077 (g-band) for MD08.

I also smoothed with a gaussian, not the kernels that went into the PS stack. 62 62 63 [[Image(md08_077_comparison_stack , 600px)]] [[Image(MD07_gband_sdss.jpg, 600px)]]63 [[Image(md08_077_comparison_stack.jpg, 600px)]] 64 64 65 65
