DOC: Validation 3D ellipticity distribution

[Lucia-Fonseca]

Description

Including the validation plot for the 3D ellipticity model (Ryden04) would add extra value to the examples page.

Inputs

• We could reproduce the Ellipticity of the Disks of Spiral Galaxies and validate with SDSS data as done by @ntessore here.

Outputs

• Histogram: Distribution of axis ratio 𝑞_{am} for exponential galaxies in the SDSS DR1.
