    v3 v4  
    116116 * generally edge skycells have issues, need better containment of those still. (see core coverage below). g,r has additionally ratty edge skycells.  
    117117 * like others, greater % of inputs rejected (20-30%) so per pixel input is less, but still of order 30 inputs per pixel 
    118  * 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. 
     118 * 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 (ie s083r, and a bit s011i, s017g) 
    119119 * 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  
    121  * skycell.087 in y,z,i may be odd. skycell.028 in g-band likely undersampled. 
    122  * appears sky in some edge skycells my have offset. 
    123  * bad cell segments primarily in y-band skycell.042,052,057,063  from ota14, cell 31 
    124  * poor/bad cell in all filters for skycell.044, some 033. 
    125  * misc clusters of ghosts in g-band (046,052,053,061), some in r-band (042) 
    126  
    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 
    128120 * skycell details:  
    129   * y: s032,042,052,062,063,083 cell print through problem; s034 bright junk; s044 center/dither spot; s003,004,040 cell odd/bright chunks on edge 
     121  * y: s032,042,052,062,063,083 cell print through problem (from ota14, cell 31); s034 bright junk; s044 center/dither spot; s003,004,040 cell odd/bright chunks on edge 
    130122  * z: s005,006,040 undersampled, messy edge; s034,062 bright junk 
    131123  * i: s006,040 undersampled, messy edge; s015,034,062 (057 less) bright junk

    137 Core 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)
