HST 14164+5215 is a pair of images symmetrically placed around a brighter galaxy.
The lensing galaxy, has an apparent color (V-I)=2.0 mag.
The lensed source appears to be point-like with a color (V-I)=0.2 mag.
The impact radius is 0".06.
The image magnification is about 2.3 magnitudes, making each component about 0.8 mag brighter than the point-like source.
The model gives a very good fit with a normalized chi² of unity.
