    114115== Problems  == 
    115  * generally edge skycells have issues, need better containment of those still. (see core coverage below). 
     116 * generally edge skycells have issues, need better containment of those still. (see core coverage below). g,r has additionally ratty edge skycells.  
    116117 * like others, greater % of inputs rejected (20-30%) so per pixel input is less, but still of order 30 inputs per pixel 
    117118 * some convolved stacks have poorer FWHM PSF but not significant enough to be likely improved by reprocessing using DEEP_STACK config as in earlier MD fields. 
     119 * as this is a field with a large center offset, the center is more contained in skycell.044 and has the degraded FWHM in gri  
     120 
    118121 * skycell.087 in y,z,i may be odd. skycell.028 in g-band likely undersampled. 
    119122 * appears sky in some edge skycells my have offset. 
     
    122125 * misc clusters of ghosts in g-band (046,052,053,061), some in r-band (042)

     127 * occasional edge higher but not too excessive except s083r, and a bit s011i, s017g; terrible gri center s044 likely since all in 1 skycell and not split over 2-4 
     128 * skycell details:

     137Core coverage is the default set -- one of the larger shifted pointings so very different from normal distribution of skycells (also see detection efficiency maps below)
