VizieR Online Data Catalog: Dust effects on photometric parameters in spirals (Pastrav+ 2013)
Abstract
The tables from appendix A (tablea*) list the corrections for projection effects on bulge- disk decomposition, the tables from appendix B (tableb*) list the corrections for the effects of dust on bulge-to-disk decomposition, while the tables from appendix C (tablec*) list the corrections for the effects of dust on single Sersic fits of galaxies containing a disk and a bulge. The corrections in Table A and B are given for the scalelength/effective radius, Sersic index and bulge-to disk ratio of disks and bulges. The corrections in table C are given for the effective radius of composite systems. The corrections are given as a function of inclination, central face-on optical depth in the B band taufB, and wavelength. The parameter space covered by this is as follows: taufB={0.1,0.3,0.5,1.0,2.0,4.0,8.0} wavelength (in Angstrom): 4430,5640,8090,12590,22000.
The corrections are provided for photometric fits done with the following functions: i) exponential+Sersic functions for disk and bulge ii) variable index Sersic functions for both the disk and the bulge iii) single Sersic fits The corrections are provided for systems with exponential bulges (i.e. Sersic index fixed to unity) and de Vaucouleurs bulges. The corrections can be used together with the ones given in Pastrav et al. (2013, Cat. J/A+A/553/A80), using Eqs. 10 and 11 from Pastrav et al. (2013, Cat. J/A+A/553/A80). The photometric parameters for which corrections are listed are as follows: R - the exponential scalelength Reff - the effective radius nsers - the Sersic index B/D - bulge-to-disk ratio of the composite system To facilitate access to the information and to allow the corrections to be calculated for any inclination, the corrections are presented in the form of polynomial function fits. For all cases the fitted function is given by Eq. 16 of the paper. (70 data files).- Publication:
