J-band

background = iterstat.cl with 5*sigma taking the mean value

SEXtractor parameters

 DETECT_MINAREA   5.            # minimum number of pixels above threshold
 DETECT_THRESH    5.            # <sigmas> or <threshold>,<ZP> in mag.arcsec-2
 ANALYSIS_THRESH  5.            # <sigmas> or <threshold>,<ZP> in mag.arcsec-2

 DEBLEND_NTHRESH  32             # Number of deblending sub-thresholds
 DEBLEND_MINCONT  0.005          # Minimum contrast parameter for deblending
 BACK_TYPE	 MANUAL
 BACK_VALUE	 background      # FROM ITERSTAT.CL
