tar cvf surface_brightness_profiles.SCII.tar */*prof Column 1: a, the elliptical aperture semi-major axis (arcsec.) Column 7: mu_I, the I-band surface brightness (mag/sq. arcsec.) the uncertainty range for mu_I is from Columns 8 & 9 and is [ u_I-e_mu_I_brighter -> mu_I+e_mu+I_fainter ] Column 8: e_mu_I_brighter, the uncertainty on mu_I "on the bright side" Column 9: e_mu_I_fainter, the uncertainty on mu_I "on the faint side" The other columns provide details on the isophotal ellipse fitting (e.g., # of iterations, quality of fit, # of pixels within ellipse, etc.) I could try to dig up that information if necessary.
