Bar Strengths, Bar Lengths, and Corotation Radii, Derived Photometrically for 10 Barred Galaxies
We have used photometric images of 10 barred galaxies in the B and I bands to infer geometric and dynamical parameters of their bars: their lengths, their strengths, and their corotation radii. The bar length, R_bar, is measured as the radius at which the odd Fourier components of the I image show a rise, accompanied by a blue peak in the B-I
