2MASS NGC 3198
Main script
The main script: decomp_2mass.sh
./decomp2d_mass.sh ngc3198_mosaic_[j,h,k].fits mass.sex
is calculating background using IRAF's iterstat.cl with [5,3,3]*sigma and taking the mean value. Than it calls SEXtractor.
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
It creates doEllipse_ngc3198_mosaic_[j,h,k].py file for python:
python doEllipse_ngc3198_mosaic_[j,h,k].py
All initial values for ELLIPSE task taken from mass.param mass.param file.
J-band
- Only initial PA must be set to -30, otherwise it wont give meaningful values.
