2MASS NGC 3198
J-band
The main script: decomp_2mass.sh
background = iterstat.cl with 5*sigma taking the mean value
SEXtractor parameters mass.sex
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
All initial values for ELLIPSE task taken from mass.param mass.param file. Only initial PA must be set to -30, otherwise it wont give meaningful values.
