Use two files from a profiles.sh run (Radial_Profile.Bins and profiles_full.table) to compute a mean flux growth curve using all sources. Initial the points are binned a median-smoothed, and then a smooth splibe curve is computed that can be used for applying aperture corrections.

 

% meangrowthcurve.sh  --help  

usage: meangrowthcurve.sh a.fits [-v] [-h] [-m method]  
arg1 = name of FITS image processed by profiles.sh   
Additional options: 
     -v  = print verbose comments and run in debug mode 
     -h  = show a help file and then exit 
     -m  = method (can be "none") 

% meangrowthcurve.sh 20191018T024545.3_acm_sci.fits  

The blue points with error bars are median points computed for the flux growth curve of an image using the code meangrowthcurve.sh. Beacuse N=26 sources were measured in this image, the standar error attached to eah point was quite small, and appear as small dots in the median points (large open circles). The red points are the original points from individual annuli from every ssource collected in a run of the profiles.sh code. The red line is a smoothing spline fitted to the median points for use in a lookup table that can be used to apply the final aperture corrections to magnitudes compted with the photometry code imgcat0_apmags.

Just for completeness, and because I always seem to forget this stuff, here is the files I used to make this plot.

 
 
meanGC.table 
  The median and mean statistics for each ring from each profile measured in 
  the image. These are the blue points in the plot. 

profiles_full.table 
  The original profile points from eacg source measured with the profiles.sh  
  code in a step previous to meangrowthcurve.sh. These are the red points in 
  the plot.

GCspline.table 
  The spline-smoothed growth curve. This is the red line in the plot.
