    121121== Problems  ==
    122  * generally edge skycells have issues, need better containment of those still. (see Core coverage below).
    123  * some convolved stacks have strange/poor FWHM PSF -- reprocessed using DEEP_STACK config with lighter input restrictions so may not have best FWHM, but 99% on the edge of field so won't anyways. Seems to be fewer problems compared to previous refstacks.
    124   * g: --
    125   * r: --
    126   * i: --
    127   * z: --
    128   * y: --
    129  * bad cell arc in primarily skycell.033,024,025,026,047 y-band from ota14, cell 31. Not really seen in skycell.036 like others. ??
    130  * poor/bad cell arc in primarily skycell.064 g-band (and less so in other filters) from ota43, cell 54? see [wiki:MD10.refstack.20120705] where was in skycell.054. ??
    131  * misc clusters of ghosts in g-band
     122 * generally edge skycells have issues, need better containment of those still. (see core coverage below).
     123 * like others, greater % of inputs rejected (20-30%) so per pixel input is less, but still of order 30 inputs per pixel
     124 * 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.
     125 * skycell.087 in y,z,i may be odd. skycell.028 in g-band likely undersampled.
     126 * appears sky in some edge skycells my have offset.
     127 * bad cell segments primarily in y-band skycell.042,052,057,063  from ota14, cell 31
     128 * poor/bad cell in all filters for skycell.044, some 033.
     129 * misc clusters of ghosts in g-band (046,052,053,061), some in r-band (042)
