 === Photometry on these new stacks ===
 
-[[Image(heather.jpg,400px)]]
+Here we show the comparison with SDSS for four stacks of MD08 skycell 041 i-band. The original 200907 release; Paul's nightly stack 25532 (8 frames); Heather's new stack of 41 frames; Paul's version of 25532 fixed to remove the problem of clipped stars. The x-axis is SDDS magnitude - blue crosses are SDSS classified stars, red circles SDSS classified galaxies. We have used the Panstarrs PSF mags for this comparison, so don't be surprised that the galaxies don't agree.
