Photometric decomposition of barred galaxies
Listed in IVOA Registry (Virtual Observatory)
We present a nonparametric method for decomposition of the light of disk galaxies into disk, bulge, and bar components.
Description
We have developed and tested the method on a sample of 68 disk galaxies for which we have acquired I-band photometry. The separation of disk and bar light relies on the single assumption that the bar is a straight feature with a different ellipticity and position angle from that of the projected disk.
Here we present the basic method, but we recognize that it can be significantly refined.
