v10 v11 24 24 === Photometry on these new stacks === 25 25 26 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.26 Here we show the comparison with SDSS for four stacks of MD08 skycell 041 i-band.
